Tha Business is a self defense kit designed for those who find themselves in sticky situations. “I thought it’d be pretty knarly to design a deck of self defense cards. Things such as brass knuckles, pepper spray, pocket knives & whistles to name a few,” says the designers. All this from a few inspiring trips thru San Francisco’s sketchier neighborhoods. I don’t advocate violence even in self defense (ahem – brass knuckles) but these are slick and unassuming self defense weapons.
