One Sterilized Cannula Piercing Needle by Precision Needles — 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 sheathes, providing a stable route for jewelry insertion during the piercing procedure (also known as cather needles). 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 needle is pre-sterilized with Ethylene Oxide (EO) gas and packaged individually in a tri-beveled sterilized pouch with lot number and expiry date.
