If you go to Kaiser Permanente if you look around on their desks you might find popsicle sticks which can be used for bridges cabins with a little imaginaton anything with wood.Also the time I went I saw weird looking purple stick with bristles like a tooth brush which I had no clue the doc. would use it for,but the idea of good cleaning brush came to mind for an airbrush scrub off paint in a cup cleaning a figure anything.I just grabbed bunch Im sure they dont mind.Good Luck

Kaiser Permanente?

I think It's an HMO I can usually find similar items at work, but I'm careful to only take the stuff we can no longer use on paitents and that would be thrown away.
