I was wondering if anybody has had any bad experiences with storing their casino chips in the 2x2 cardboard flips? Most of my better chips are in Air-Tites, but I do have quite a few that are in flips. I used to use the binder that held 200 chips in plastic pockets, but I stopped using those as some of the chips "stuck" to the plastic pockets over time, mainly the inlays of the Bud Jones type chips. I just wanted to see if there are any negatives to using the flips for long term storage. Thanks
