What should I use to paste the certificate without leaving a trace?

Sticking the certificate with scotch tape won't leave any trace. It is easier to take it off with transparent glue, and the damage to the wall is less.

Taboos for using adhesive tape:

First, the use of tape method

To stick the certificate on the wall without damaging the wall, you can stick it with ordinary transparent adhesive tape. Just roll the scotch tape into a small circle and stick it on the four corners of the certificate, and then stick the certificate on the wall. It can also be attached to the thinnest and smallest double-sided tape.

Second, matters needing attention

Scotch tape is poisonous. The main raw material of scotch tape is generally PVC, which is PVC! The chlorine in it has a pungent smell and is very corrosive. PVC is the kind of material outside our general wires! The irritating smell of inferior PVC is very heavy! It is also very harmful to the human body! Note: Because the adhesive tape is poisonous, it is recommended not to bite directly with your mouth.
