LVLY Wrist ruler
The Wrist Ruler by American company LVLY is a leather wristband with engraved measurements in inches and centimeters. The perfect accessory if you, too, can never find your measuring tape when you need it for your gauge swatch, your knitting project or some impromptu home improvement.
Choose your size based on having the wrapped twice around your wrist twice and give it some extra length if you want it fitting loosely. An extra centimeter / ½" should be allowed for the stud closure.
