4 sided buffing block to smooth and buff the surface of the nail before topping with the Glossy Top Coat.
PS - these are not super long lasting, but they are GOOD! You'll get maybe 5 sets out of each one, I'd say.
White buffing block .
Very happy with them the sides of them are not to sharp , so very comfortable around the cuticle, and leaves nail nice and smooth,
A must have file
These five you a beautiful smooth finish.
