Sterex Insulated Two-Piece Needle F31 Short – Sterile, Single-Use

The principle behind the Sterex insulated needle is straightforward: by coating the shaft in a non-conductive material, the electrical current is directed specifically to the exposed tip — rather than distributing along the full length of the needle. This focused energy delivery is why many electrolysis practitioners choose insulated needles for work where precision targeting matters.

The F31 Short is made from diamond-drawn medical-grade stainless steel with specialist insulation coating. Short format for facial and fine-hair work. Compatible with Sterex two-piece needle holders. Made in Birmingham. Supplied in packs of 50, individually wrapped, sterile, single-use.
