After nearly a lifetime of getting Costanza’ed in the bottom by my wallet, I began to use this 35¢ tool and have never looked back, so to speak.
It firmly clamps bills and even cards in place until use, is easily removable and has caused much envious conversation.
The only drawback is that I bought a box of 12 (the smallest I could find) and am still using the same one after six years.
Appropriate technology rules!
