While smaller, I have been using the some of the plastic bases/holders that the WizKids Heroclix Capt. America figures were shipped in. They are just the right size to hold a Reaper Pro Paints pot real snug fit) and the new GW Citadel paint pots (slightly looser fit then the Reaper paint Pots, but still they are a semi snug fit). I am going to try and see if I can get some more to also use as small palettes for mixing and to hold bits that the paint is drying on (like the small pill bottles I made from a toothpick), that one side with some paint not on wont be a big deal.
