I designed this Hook specifically for getting my Backpack off the Ground. Simply Slide it on any Wall you can acces and get yout Bags of the Floor. There are multiple Versions ranging from a 40mm Wall to a 10mm Wall. Also there are Thick Hooks (35mm) and slim versions (20mm).

I tested the thick 40mm Hook. It holds at least 7.5kg.

Note: The versions all are 1mm wider so there is room to slide it on a wall without damaging it. You can use felt to even it out.
