Pretty much the main attraction here is the pipette. The cup looks like it was meant to be a lid to some kind of spray can or something, There are reinforcement ribs on the inside that could cause you to knock a chunk off of the end of your stir stick if you're not careful. Most people that I know that mix paint, and myself, typically use some kind of plastic artist's pallet or mix right in their airbrush vessel. I'd just buy a bulk pack of pipettes and save yourself the trouble of tossing the plastic cups in the trash.

I found the 1 oz shot glass style cups better for mixing etc than these 1/2 oz cups since these do not have measurement markings on them.

these made mixing so easy, only complaint i had is it felt like paint would sink into the edges preventing a really solid ratio mix, if you are mixing alot then you wont have a problem.
