A reusable hook made of a unique suction sheet called "PitaSheet", which adheres well to smooth surfaces. Can be used on smooth surfaces such as glass, stainless steel and painted metallic surfaces (such as refrigerators). To reuse simply spray with water and wait 30 minutes, and the hook will easily come off.
In the past, I had damaged walls using conventional hooks and had been unable to use magnetic ones because the walls were not magnetic. I discovered this magical material just as I was talking about creating a more user-friendly hook. I hope this hook, with its mysterious suction power, will be of some use to you.
Only works on flat, non-porous surfaces. Doe not work on materials such as brick, concrete, plaster, etc.
