A specialist finishing bit originally created by Willow engineered to polish, refine, and perfect the skin at the final stage.

The Diamond Polisher Extra Fine is a true Step 3 finishing tool, designed to be used with cuticle oil to gently exfoliate and smooth the surrounding skin - eliminating hangnails and creating a flawless, high-end finish to your service.

Its large extra-fine diamond ball allows for ultra-soft contact, making it ideal for refining without irritation - this is where prep moves from clean → perfected.
