I've been using these for years I get 5-7 years out of one then toss it. They are incredibly thin and will flex when you sit down. I just counted 16 various CC's, ID's, Carry permit, and insurance cards in my wallet along with 15 bills of various denominations. It is thinner than most others empty. They actually work better with more cards in them. Mine measures 3/8" thick wtih all of that in it. If you only put 1-2 cards in each slot they don't fit tight enough and may fall out. I find that I carry some cards that I'd normally leave at home just to make them a tighter fit.
