Steel Threaded Guide Pin Taper

Isha Body Jewellery

Size Guide

Rejuvenate those shrunken piercings with this graduated insertion pin.  Match the thread to your internal threaded jewellery and screw together.  Lubricate the pin (purchase here) and slide the narrow end of the pin through whilst bracing the other side of the piercing with your fingers.  Once in place, unscrew the pin and fit the attachment to the post of the jewellery.  The cool nature of steel will add comfort to freshly stretched piercings.
