In addition to making it easy to identify paying guests in a glance, each cloth wristband is affixed to the wrist with a plastic barrel lock. Once tightened to fit, the plastic lock won't move, so the only way to remove the cloth wristband off is to cut it off. Additionally, the lock is waterproof, extremely sturdy, and will withstand several days of use. Finally, the fabric of our cloth wristbands is extremely resistant to snapping or tearing.
