Some of us are even crazier and use 2 1/2" X 2 1/2" cardboard holders. The 2X2's just don't have enough room for a chip and the writing area is too small also. I really like to be able to page thru my binders and see all of the chips in my collection vs seeing one at a time in air tights. It is a real pain but before each convention I scan a good portion of my collection (those areas that I don't have a list or price guide for) and print them out into books so I don't buy duplicates. OK, I have to admit that I still get some unintentional duplicates each year but it is really hard to keep track of 25000 chips. But I am not buying the big dollar chips so I just put them in the trader pile. I really got to work on that pile in the near future - I probably have 3000 traders to get rid of.
