Simply - Builder In a Bottle
Like it sounds, it is a builder gel but in a bottle. It can be used on natural nails as an overlay or on extensions as a builder gel. It can be used over tips or to sculpt with forms.
The difference with this product and a normal gel product is the fact that it is applied just like a normal gel polish, with a normal nail polish type brush. The only difference is you apply this one a bit thicker to build up the stress point.
