Press down hard and hold for 5 seconds after sticking. 3.How to remove -- Using hot air from a hair dryer will soften the tape and make it easier to remove.Then you can use a sharp tool to slowly lift the tape from one side and then slowly peel the tape off the surface of the object. 4. To avoid damage, do not use the tape to hold heavy objects or valuables. 5. Can be air-dried or blow-dried with a hairdryer after washing, DO NOT use any other wipes or detergent. 6.
