Ask the MB: Minimalist Wallets
A: We've previously endorsed minimal, non-George Costanza wallets. Specifically, the MAKR CARRY GOODS "One" ($60) made from free-range cattle each given a loving pat on the head before being shipped to slaughter, and Malcolm Fontier's polyurethane "Mojito" ($29) for more highly evolved types.
While Dopp certainly has a pedigree -- German immigrant Charles Doppelt invented the toiletry case in 1919 -- a magnet seems like an especially bad materials choice for a money clip. Besides potentially demagnetizing something like a room key, the clip's effectivness diminishes in proportion to the more cash an MB is carrying.
