The reason all my chips are going into air tites from the cardboard flips is because I'm afraid of warpage. I have asked many people and I may be the only one with this problem. I am noticing the flips are getting a twist to them. If you look straight down into the box you can see some are not flat, but have a twist to them. I took one out and the chip appeared to be slightly warped. Now I know many things can cause this, but I never had the problem before and I have ben collecting for 10 years now.

Anyone else notice this?
