Erica 's Refine Ball diamond tip is a must for cuticle exfoliation ! Ideal for removing dead cuticles or polishing cut or dull edges created by tweezers. 3.4 mm diameter sphere. 100% natural diamond.
PRO TIP: Not to be confused with the ''Ball Bit'' which is 2mm in diameter. The ''Ball bit'' is used to cut the cuticle and the REFINEMENT BALL with its larger surface (3.4mm) does the finishing.
Best used at 10,000-20,000 rpm with an Erica ATA electric file. RPM will vary depending on technique, electronic file and bit novelty.
