They are quite thin and flexible when you go to place them, but I can say that when you finish the application and the color and top, it's okay. Of course, I have the impression that they are not actually gel tips but plastic. Anyway, very easy to use and stable with proper placement.

Excellent product.
Very fast application.
The basic thing is that it does not require sanding because it has a groove.
It has elasticity as needed.
If you make a mistake, it is very easy to remove.
