A crystal sticker is a three-dimensional sticker. It is also known colloquially as bubble sticker, 3D sticker etc. As we know there is no exactly specified name for it so far.
The crystal sticker is highly resistant to both indoor and outdoor conditions.

What is a crystal sticker?
It is a normal sticker coated with a special liquid substance, polyurethane, which, depending on the composition of the mixture, hardens into a very hard or slightly soft surface with a 3D visual effect. As the print is under a layer of polyurethane, the colours do not fade and the sticker stays beautiful for a very long time, both indoors and outdoors.

Where is the crystal sticker used?
The crystal sticker can be used wherever you wish. It is very suitable for name tags, advertising signs, electronic equipment, cars and anywhere else where the surface is smooth enough (the sticker may come off on a curved surface).
