Staples that is. I use 2 1/2 X 2 1/2 cardboard holders for all of my chips and use 3 staples per holder. Early in chip collecting "career" I bought a pack of 10 - 5000 staple boxes and I just finished the last box today. So that means I am well over 15K chips now. Now if I just had the time to get rid of the 1000+ duplicates I have. Hopefully I can concentrate on that when get thru with cataloging the 400 chip collection I just bought.
