These are beautiful paints! But when I opened the box and looked at all the plastic bottles I thought what’s the point now? The same types of solvents, resins, flow enhancers, curing agents and so on are used to make the bottles, as are used in plastic based acrylic paints. So what’s the point of buying this paint ? If the company used aluminum tins or tubes I would have kept this set. I’d like to see them make efforts to correct this discrepancy. (I don’t use powdered pigments with animals in our home btw)
