I needed to get my SU cardstock scraps out of the zip lock bag and into something a little more organized. I found this accordion box last month at Hobby Lobby that works great. I was going to organize by color family and then by color, but it was just easier to do it by color - reds, greens, blues you get the idea. I don't know the exact dimensions off hand, but I cut a lot of 8.5x11 paper in half for my cards and a half sheet fits perfectly in it so it is a great size. It was 9.99 and I used a 40% coupon so it was only 5.99. They have a couple different sizes and since I picked my sticker collection down from hundreds of sheets to just a handful, I might buy another one in a different size to hold those.
