How We Handle Shipping Issues

Once an order leaves our facility, delivery is handled by the selected shipping carrier. Any delivery issues must be addressed directly with the carrier, as they are responsible for transporting the package to its destination. For USPS shipments, we’ve found that contacting your local post office is often the most effective first step.

You may track your shipment or submit a missing mail claim through the carrier used for your order—either the U.S. Postal Service or UPS.

While we make every effort to process and ship orders promptly, we are not able to retrieve or locate packages once they are in transit. In the event of a delay or loss, we ask for your patience while the carrier completes its investigation. Replacement items or refunds can only be issued after the carrier has made a formal determination.

After an order leaves our facility, responsibility transfers to the carrier, but we’re glad to offer support and direction should any delivery issues occur.

If your order arrives damaged, please contact us within 10 days of delivery. Include your order number and photos of the damaged product and packaging. 

We do everything possible to make sure acrylik paint and medium will arrive undamaged in winter. We insulate packages and add heat packs to help ensure paint will not freeze in transit, however, we cannot guarantee that acrylik paint and medium will always arrive undamaged. We will not replace or refund acrylik paint that has been ruined by freezing temperatures. 

If an order is marked “delivered” by the carrier but you have not received it, please let us know, but do note that we will insist you make every effort to find the package on your end, including checking with neighbors and waiting at least 2 more days for delivery. If the package does not show up, we will assist you in starting a trace with the carrier or make another determination about how to handle the issue.

 

Return Policies

We offer full refunds on any defective or damaged products. We also offer full refunds (less shipping costs) on elective returns if the product is in re-sellable condition (including the packaging) and the return has been made within 3 months of the purchase.

Acrylik specific: We do everything possible to make sure acrylik paint and medium will arrive undamaged in winter. We insulate packages and add heat packs to help ensure paint will not freeze in transit, however, we cannot guarantee that acrylik paint and medium will always arrive undamaged. We will not replace or refund acrylik paint that has been ruined by freezing temperatures.

International Shipping

If you’re ordering from Europe, Canada, Australia or New Zealand, please click the appropriate link to visit the international website for your region - these are operated by third parties but all products were made in the USA . We normally ship with either FedEx or UPS for international orders, and the order typically takes 2-3 weeks for delivery.

PRODUCT FAQs

Does it yellow over time? 
We sell walnut oil because it is less yellowing than linseed oil although there will be slight yellowing over time.

When mixing your own oil paint, many people choose to use Liquid Gold Hempseed Oil with the white pigments only (instead of walnut or linseed oil), so that the white paint will never yellow. 

A common cause of yellowing is called "dark yellowing" and happens when pieces are stored in the dark for too long. The good news, though, is that placing the art piece back in direct sunlight will reverse the yellowing. This reversal takes anywhere from 1-7 days.

How long does it take to dry? 
Walnut oil dries slowly and can dry to the touch between 4-14 days depending on the humidity of your area, the type of pigment used and how thickly it was applied.

Is it refined? 
Yes. It is pure, expeller pressed walnut oil, so no other chemical or oils are introduced in manufacturing or bottling (when it is refined it is naturally "bleached" with clay which is just a natural filtering for color and clarity and there should be no allergen potential because it is refined). No hexane or solvents are used at all. 

How does it compare to linseed oil? 
You can use linseed oil interchangeably. We use walnut oil because it's higher quality and is less yellowing over time. But linseed oil dries faster which some people prefer. 

How does it compare to poppyseed oil? 
Historically, some painters mixed their white pigment with poppyseed oil instead of walnut or linseed because it never yellows and is the clearest of all oils. 

How does it compare to sunflower oil? 
Sunflower oil can be used but it dries much slower than walnut oil (which already dries pretty slow) and some sources say that it may discolor your painting or yellow over time. 

Is it flammable? 
All natural oils are potentially flammable if left on a rag in a hot area. It's suggested that you store oil soaked rags in a metal bucket with a lid and submerge in water if you're not disposing of them right away. Artists have many techniques of safely storing or disposing of their soiled rags - you'll find a lot of tips on google and artist forums.  

Can it be used for a wood stain? 
Most woodworkers who are staining outside wood furniture just mix our natural pigments with walnut oil and brush it on and then wipe with a dry rag. If you want the paint more opaque just add more pigment or don't wipe with the rag. It will bond well with the wood. It will completely compost and biodegrade because it's just earth and oil. Here's a tutorial with other natural wood staining recipes as well. We also sell a Natural Wood Stain & Varnish Set.

What about clean-up? 
Large amounts of oil or oil paint should be disposed of according to your city’s local ordinances.

To wash oil paint from your hands and body:

Option 1: Use Pinerite Natural Hand Cleaner.

Option 2: Rub a small amount of oil into the paint on your skin, then wipe off with a rag and wash with soap and water.

To clean brushes:

Option 1: Pour a small amount of Eco-Solve* into a glass jar (just enough to cover the brush bristles if you dunk your brush), then swirl your brush until the majority of paint comes off. Finish washing brushes with soap and water.

Option 2: Simply use pure oil, like walnut, to thin your paint and clean your brushes

Option 3: Use Murphy’s Oil Soap from any hardware store.

*You can re-use Eco-solve nearly indefinitely just like regular solvent. After cleaning your brushes, let it sit in a covered glass jar for a few days to a week and then the paint sediment will settle to the bottom. You can carefully pour the "clean" eco-solve that is on top into another container, then the paint sludge left in the jar can be wiped out and disposed of in the trash or washed down the drain if the paint is non-toxic and safe for waterways.

Simply the best!

The easiest way I can describe my paints made with refined walnut oil is that they smell like salad instead of toxic waste. Being around commercial oil paints bothers me in a matter of minutes, but my natural earth oil paints do not bother me at all. The refined walnut oil is very good quality and mixes easily with pigments to make paint or thin already mixed paint. I am very happy with it and use it every day.

I've been using this for years and it's worth every penny. I love the non-yellowing and it improves drying time.

While doing oil painting this product is must. You can use it instead of linseed oil . It can be used to clean brushes also as well as to create a lean layer of colours.

Great brand and quality! Best on market!

This is a great product if you want to mix your own oil paints. I also buy pigments from this brand and make my own paint. You can control the consistency of your paints and they are 100% natural so you won’t have to worry about chemicals. The quality is great as well, better than any other oil paint brand I’ve tried. Only downside is the time it takes to mix your own paints.

Best painting oil & also good for cleaning brushes.

Easy to use. No volatile fumes. No yellowing.This walnut oil is ultra filtered & no additives. It is oil from nuts. Walnuts.Other plant based oils that are used for artist oil paint are:Linseed(flax)SunflowerPoppy SeedMajority of Artist oil paints are made fromplant based oil + pigment.Some have chalk fillers added to keep costs down.All artists commonly used paints, watercolor, acrylic, or gouache or oil etc,are GENERALLY made from the same families of pigments & fillers.

Has changed my art practice:pray:

I switched to walnut oil and it has changed my art practice. It is so smooth I really have come to further appreciate the beauty of pigments. I used to lay paints on thick and it occurs to me now I was reaching for something I now have with the pure pigments and walnut oil (making my own too, thank to Natural Earth Paint's) I am using smaller brushes, working thin. It's wonderful. Total convert. Made the switch initially because walnut oil's fire point is so high it isn't considered combustible. Temps have to be more than twice as high as for linseed oil, for example, before it combusts. That's added safety for my studio, my garage where the garbage bins are, and the landfill. We don't need more fires!

Good for oil painting.

I was happy with the oil and had no problems. Bit expensive but lasted me 2.5 months of bi weekly painting.

Great Walnut Oil!

I wanted to use something non-toxic to thin out my oil paints while painting and this works great, I will defiantly keep using this product.

I love it! I switched

I love it! I switched over from linseed oil and walnut oil is so much easier to work with and doesn't have an odor. The only issue is that I wish that it come with a pouring spout. It's hard not to waste it when it doesn't pour precisely out of the glass bottle. It would be so great if it came with a spout!

the perfect medium

What do I like most about the Walnut Oil? It is non-toxic, to me, to those who happen to be near when I paint, and to the earth.

I also like that I'm painting with the earth, and walnut oil is a part of that!
