I carry a guitar pick in my wallet.
Just checked my wallet: 9 picks (in the built-in zippered coin purse).
3 of the big Fender triangle bass picks, 4 dunlop max-grip 1.14mm, 1 dunlop nylon .38, one dunlop nylon .46 and one dunlop nylon .73 mm
Just thinned the herd!
But it does point out another weird habit I only buy wallets with coin purses built in.
