2-1/2 x 2-1/2 holders. I like the idea that I can write information on them because I dont have the knowledge of knowing where all the chips are from, etc. I put info on the back also like mold or owner information if available. I am torn since I have 8-9 casino chip binders full and its a lot of work finding the information..... To each his own I would guess.
