Natural Nail Matting: Use the softer 240-grit side before base coat application. Gently swipe across the natural nail plate in the direction of nail growth to remove the oily shine, paying close attention to the proximal fold area.

Artificial Surface Shading: After shaping your extensions or overlays with a coarser file, switch to the 180-grit side to quickly erase heavy tracking marks and flatten structural bumps before applying color or top coat.

Cuticle-Line Precision: Guide the curved semicircle edge along the cuticle zone and lateral side walls to smooth out product transitions smoothly without scratching the client's skin.

De-Dusting: Clean away all filing residue using a professional manicure brush and a lint-free wipe soaked in gel cleanser before moving to the next gel step.

Sanitization: After each service, remove all dust from the buffer, spray it thoroughly with a compliant salon disinfectant solution, and leave it to air-dry completely.
