Here is something quite ingenious. The wrist ruler! Hailing from LVLY workshop at Portland, Oregon. This made to measure wrist ruler has measurements and number engrave on the leather. It uses a button rivet for closure to keep it secure around your wrist. It can also be used as an actual ruler when you don’t have one around. it is a unique accessories that is functional.
I should have thought of this one. Whoever created this idea is creative and ingenious!
