6" electronic digital calipers. This tool measures in metric and standard from 0 to 155mm (0-6"), and switches between millimeters and inches with the press of a button. Features both internal and external measuring jaws (so you can measure the inner diameter of a hole as well as the outer dimensions of the item), locking screw, zero setting, depth measuring blade, and easy-to-read LCD display. Includes hard case. Far more accurate than a measuring tape! Excellent tool for helping you decide what size jump rings will go with your chain links, or what size cord you need for your beads, and other jewelry making dilemmas. If the display starts to blink, that's your "replace battery" warning. (Battery is easy to replace, and usually lasts weeks after it begins to blink.)
