Love the new pots for one reason. My paints no longer dry up over the course of a couple weeks. I hated that about GW's paint pots ever since they left the "white" pots way back in the day. I still have some old colors from way back that are still usable some 16 years later. None of the black lid pots have lasted even close to that amount of time. More like 16 daysAnd for how expensive the paints are for how little you get, I expect them to last a long time.
I never paint out of the pot and just transfer to a palette, so these work great for me!
