These styluses are designed to work with scanners, so you can easily reach the screen while keeping the stylus tethered. The tip of each spare stylus glides across your screen to precisely activate the right area without scratching or otherwise damaging the surface. The stylus tip is manufactured with ultra smooth surface to ensure the tip is free of burrs and parting lines. Elastic tether is coiled and remains close to the terminal to minimize the chance of snagging or tangling on objects. The coil tether stretches easily to allow the user to easily use with terminal.
