The Compact Pin Removal Tool for Metal Watch Link Straps is a small red device that helps you resize metal watch bands by removing link pins. By turning the knob, pins are released safely, making it simple to remove the necessary links without applying force. After achieving the desired fit, use the same tool to push the pins back into the strap. A second photo demonstrates how to use the tool. This toolkit is recommended to accompany any strap that requires link removal to properly fit your watch strap. Note: This tool is intended only for removing links from metal straps and other straps that use pins and links for resizing. It cannot be used to remove or swap the strap itself from your watch, which in many cases can be done by hand depending on your smartwatch.
