It's been a while I've been using 35mm film cans for acrylic paints mixing and thinning.

Airtightness of these little things is unbelievable. I can keep a few drop of thinned paint for days, without seeing it drying.
I chose Fujifilm cans, as they are translucent, which is handy to see what's in the can. The beauty of this tip is that it's free: I asked people from a local photo shop to keep empty cans for me. After a few days, they were kind enough to give me a plastic bag full of cans!
Keep modelling!
Cheers,
Laurent
