Wrist Rulers
Handcrafted just across the river in Portland, OR, the Wrist Ruler is the tool you didn't know you couldn't live without. Providing measurements in both inches (down to a 1/16th of an inch) and cm/mms (down to 1mm), you will be amazed at how handy it is once you start wearing one.
At 18 inches, the Wrist Ruler wraps comfortably around most wrists twice.
