Titanium N/A 2mm ball Nostril Each piece sold individually. The Titanium Nose Screws are simple yet high-quality pieces designed especially for nostril piercings! Nose screws have a small hook at the end of the post to hold it in place. To insert it, you "screw" it into your piercing, hence the name. We recommend using our to help get it into your piercing. These nose screws are implant grade titanium. Implant grade titanium is both hypoallergenic and bio-compatible. Bio-compatible titanium resists wear and tear due to bodily fluids. These traits make titanium great for body jewelry, subdermal implants, and medical implants. Titanium must be polished for body jewelry. Our titanium jewelry is always mirror polish because titanium is porous. While porosity is great for subdermal and medical implants, it's terrible for body jewelry. Being porous allows the tissue to attach to the metal. We prefer our jewelry to be a little less of a commitment than that. As we mention at the beginning, Titanium Nose Screws are a favourite for nostril piercings. Show us how you chose to wear yours with #BodyModsFamous on Instagram. We LOVE seeing our jewelry out in the real world. Finally, don't forget to follow us on and for updates on new jewelry, product info, sales, and more.
