Avoid direct contact with door handles, switches, keypads and many other objects with this non-contact door opener keychain. With its unique two-hole design, it allows you to have four different grip styles. Top grips and thumb levers provide more leverage than other designs, while the internal tooth surface provides the necessary friction to be usable. Each opener weighs only 4 grams, making them ideal for keychains, pocket use, laptop bags, without adding any noticeable difference in weight. The key ring hole placement is designed to hold keys securely in the hand and provide increased leverage. Also works well at the end of a lanyard.
