Thanks for the input, much appreciated. I made a post on the swapshop

For further details, I got a little over 100 paints. I think some have separated a bit, I don't know if there's anything to be done about that, if they can be remixed. There are some duplicates of colours because of painting sets I'd bought.
I got some garbage cheap brushes, a painting handle (don't remember what make and there's no branding on it, so I'm guessing a cheap one), a citadel mould line remover, some green stuff world containment moulds for round bases, a couple of odd miniatures I've bough/backed on kickstarters that I'm happy to toss in. I also have most of the Gloomhaven miniatures (the reason I'm getting rid of all of this stuff is that the person I mainly played with died and so the miniatures for the characters we were using are not included)
