One box of 50 Cannula Needles Pick Size — Sizes 18g, 16g, or 14g The European method of body piercing uses cannula needles rather than hub-less hollow body piercing needles. Cannula piercing needles are hypodermic needles that are encased in plastic sheaths, providing a stable route for jewelry insertion during the piercing procedure. Each Precision Sterilized Cannula Piercing Needle is precision-machined from surgical stainless steel, and a custom emery wheel is used to cut the tip for the sharpest point available on the market. Each tri-beveled needle comes sterilized and pre-packaged in a pouch. This listing is for a box of 50 Sterilized Cannula Piercing Needles in 18g (~1.0mm), 16g (~1.2mm), or 14g (~1.6mm). Please see the table below for technical dimensions for each gauge.
