Review on Multi-Purpose Adhesive Reusable Drilling Anti Slip Organizer by Joseph Pudic

Instructions not included. It's very simple I know, but I think it makes a difference whether you glue the U up or the U down. The clip has an open groove on the underside near the breaking edge and a closed groove on the opposite side. So far it looks like the clip fits better when slid to the closed side, but then my fingers might not be strong enough. I do not know. Although they work. Let's see how long the stickiness lasts.
