I went to my local dollar store today to buy party supplies for my grand-niece's birthday. While I was there I saw a round plastic pencil/paint brush holder. For $1, I thought "why not?"
I got it home and assembled it. It holds 49 pencils or paint brushes (more since you can fit more than one paint brush in a slot).
It's as nice as many that I've seen on Amazon and a lot cheaper.
