Making repairs in the home require a set of tools, and Dave and Calvin Laituri have created four cards which double as a set of ‘Tuls’.
Each card has grooves on them which double as a set of tools like a spoke wrench, a bottle opener and a pry bar.
It is also flat enough to fit into a wallet and can be hooked on one’s house keys, just in case emergencies come up.
