[With Taper Pin ]: Check out the instruction image to figure out how to set up your threadless flat back jewelry with Insertion Taper Pin if you're having trouble pushing in. Most push pins are already pre-bent, but just in case they straighten out, you can gently bend the pin against the tube post before inserting it

[Created for Sensitive Skin]: The whole piece is made of G23 F136 solid titanium, which is recommended by The Association of Professional Piercers as implant-grade metal for fresh piercing. It's hypoallergenic and nickel-free, so it won't cause any allergic reactions. Medical titanium jewelry is known to speed up the healing to stainless steel when it comes to piercings. According to research, only 0.6% of the world population are allergic to titanium

{Size Buying Guide}: The available post length is 6mm (1/4 inch). Just choose the size based on your previous experience, as there might be individual differences depending on your ear anatomy. We have more detailed instructions about sizes in the description page

[Multiple Use] :The 20g size is not only commonly used for nose studs, but can also be worn as flat back earrings in other piercing locations as the lobe, tragus, helix, and conch piercing jewelry

[24/7 Comfort and secure]: You can totally use it as comfy nap earrings while you sleep, thanks to its poke-free design. It won't irritate your skin at all because the flat backs sit flush against it. Unlike those ball back earrings that always seem to unscrew themselves, this one will stay securely in place if you push the pin firmly into the post. Plus, compared to L-shaped or corkscrew nose rings, threadless flat nose studs are hands down the most comfortable nostril piercing jewelry
