I never use the soft plastic flips or any plastic flips at all. Some of the smaller ones fit into the 2x2 paper
Flips with the clear round center. I don’t store chips in the plastic flips either especially the soft plastic as you can see gets nasty and melts down like a bad plaque.
I store my plaques and some jetons between cardboard dividers in a cardboard box with big desiccant bags on top. In a safe place. Away from environmental changes. Even then I’ve had some plaques sweat out and bubble ? Some just do this I think from what they were made of chemical reaction that can’t really be stopped unless you spray lacquer them. I talked to Klaus a Monte Carlo collector and he shellacs them.
Good luck
This worked for me but now I’m putting them in air tights which a lot of jetons just won’t fit in either.
Good luck
