[Size Guide] : The available post length is either 6mm (1/4 inch) or 8mm (5/16 inch). 6mm is the most common size for a nose stud, and it can also be used as cartilage earrings in places like helix, conch, flat, and tragus. If your ear piercing isn't fully healed yet or if you have thicker earlobes, it's better to go with the 8mm option just to be safe. And if you're looking to add one flat back stud to your earring stack set, then starting with the 8mm size would be a good choice

[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 grade titanium jewelry is known to speed up the healing to stainless steel when it comes to piercings. It is a premium metal which is also used to make the Iphone 15 pro phone frame

[Jewelry Change Guide]: Check out the instruction manual to figure out how to set up your threadless flat back jewelry. It takes time to learn if you are not familiar with this new flat back earring structure. If you're having trouble pushing in, don't hesitate to ask your friends or professional piercers for help with changing your jewelry. 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

[24/7 Comfort and secure]: You can totally use it as a comfy earring for napping while you sleep, thanks to its poke-free design. It won't irritate your skin at all because the flat backs sit perfectly flush against it. Plus, compared to L-shaped or corkscrew nose rings, threadless flat nose studs are hands down the most comfortable and long-lasting jewelry for your nostril piercing

[Package] This comes with a cool eco-friendly cloth pouch to prevent fake "The Jewel Pick" products, along with an instruction manual for threadless earrings and a 20 gauge titanium flat back nose stud. The 20g size is not only commonly used for nose rings, but can also be worn in other piercing locations like the lobe, tragus, helix, and conch. So it is a perfect gift option for holidays like Thanksgiving and Christmas day
