Frequently Asked Questions

What is the backfill technique?
A method for refilling French nail enhancements, where the old smile line is milled out and a new, precise line is created – instead of completely rebuilding.

What comes after milling the smile line?
Applying the white French tip with French Paint or Boomer White.

Why is the small size important?
It allows for precise, controlled contours for an exact, repeatable smile line without slipping.

Is this bit also suitable for initial nail enhancements, not just backfill?
It is primarily optimized for milling during backfill; larger shaping bits are more suitable for initial nail enhancements.

How do I clean the bit after use?
Remove residue and disinfect or sterilize according to salon hygiene standards.
