50 GMS EACH- BUILDER GEL FOR GEL NAIL EXTENSIONS. AVAILABLE IN TWO COLOURS How to use Gel Nail Extensions? Here is a way of how it works. A clean and lightweight layer of gel is applied to the gel extension on your nail. Then you will have to place your natural nail, with the nail extension on top, under the LED light. The gel will act as a bonder, curing underneath the LED light, so that the extension and your nail adjust themselves and looks like a whole nail and do not make it look as if they’re an extension above the natural nail. They are super effective and quick to use and it is easily dried and harden up. It fits perfectly making it look like a natural nail as a whole.
