Amazingly aggressive sticky tape! Extremely sticky adhesive that replaces all other double sided mounting tapes and fixatives. Non-hardening and permanently flexible. Holds incredibly strong. Yet easily removed when no longer needed and leaves no residue behind. Industrial strength technology developed for the automotive and movie industries, but re-engineered for consumer use. Comes in a very cool metal tin, about the size of a hockey puck, that is kind of old timey and will be of use long after the tape is gone. .5" wide × 20' long.
