 You just put your paint in there and use it when you need to. And then when you're done, you just leave the lid off, let the paint dry, peel it out, and use it again. Excellent. This is so cool. I mean, I work with inventors, obviously. So, you know, people have been talking about doing this forever. How long have you been working on this? I'm sorry if I'm going to go back to some inventor questions because, hello, that's what I do. So how long were you working on this before you finally got it into the marketplace?
