3.It can be adsorbed on the smooth surface, easy to pick up 

4.For example: glass, metal, ceramic tile, computer screen car navigation disc, furniture, etc. Which is  smooth

5.In dusty or uneven surface, please do not rush to try adsorption, adsorption object if you want to test, at a relatively low ground area to test

Q1: If the adhesive is not tight, Will it be fall?

A: Nothing to worry about, we have tested for six months, according to air adsorption principle, 

as long as the surface to be bonded is flat can not be leak.

Q2: The Case bonding surface for a long time will not be dirty?

A: Of course, long-term use will make the surface have dust and dander, but as long as you use a little water to clean it , it will like new one 

Q3: Case with a long gray sticky surface, the surface is not strong adsorption, how to do it ?

A: With a small amount of water to clean the surface of the case, then adsorbed material is squeezed out to be reused after 3-5 minutes dry, it will like a New One
