A D asked:
I am going to visit my sister for a month, and I want to paint while I’m there. I’m going by plane so I can’t take it with me in my luggage. Is it okay to ship oil paint (they’re in tubes) or are they considered hazardous materials? Thanks!

You will have to check with the post office; however, I think oils are bad for them. Acrylics are okay, though. You probably have to ship via UPS or Fed Ex.
you could, but I think you have to check. They are quite hazardous to a certain degree because of the oil, lead, cadmium found in them.
