Oil Paint - Recycled The area around the caps has been cleaned to allow for easy opening. Many labels have been damaged while opening the caps, but there are no hardened paints, and I think they can still be used. Since these are old tubes, if you find any that are hard, don't force them. Instead, try soaking the cap in hot water to open it, which should prevent the tube from breaking. It's also easier to clean the area around the cap after each use. #art #oilpainting #holbein #kusakabe #matsuda #paint #oilpaint #oilpainting #oil #paint #artsupplies #fineart
