Here's an easy way to keep your glasses safe, close and at the ready. Attached to a shirt (or any other thin cloth), the discreet clip provides a secure place to hook your glasses. Made from stainless steel, the clip is worn on the outside of your shirt and clings with magnets to a backing plate worn on the inside of your shirt. The rare-earth magnets are strong, so the clip stays exactly where it is placed – it won't fall off from movement.
The clip can also be attached to any ferrous surface – keep one on the fridge or a stationary tool in the shop. Accepts glasses arms up to 7/8" wide and 5/16" thick, including most safety glasses. (Note that rare-earth magnets may interfere with pacemakers if placed over the heart.)
