Nano traceless tape, water washable and reusable. Nano magic tape is a transparent nano double-sided tape made of polymer material that is traceless, washable, movable, and reusable. The surface of the material is densely covered with a large number of nano level micropores, giving the tape super strong adsorption force and easy adhesion to various object surfaces. Each adhesive surface can touch dust, debris, sweat, metal powder, etc. during use, and can be immediately reused after being washed with clean water, dried or blown dry, without affecting its original adhesion.
