It is a bit of a beyotch to screw in, so I just leave it in all the time. If I ever think it might be getting loose I just put my thumb on the flat back and spin the front towards my face. Only downside is if you leave it in is it kind of pokes you if you sleep with it in, so sometimes I do notice a little bit of skin flaming around it due to that. But this thing had been through the ringer, been in for months now, has be saturated in hair dye and still came clean and looks good, stayed in even when fidgeted with. Would definitely get again/more products for this company. ## Frequently Bought Together - FINE4U 1PC ASTM F136 Titanium North Star Piercing Jewelry for Conch Helix Flat Tragus Lobe 16G 6mm 8mm - FINE4U 1PC ASTM F136 Titanium Sword Piercing Jewelry for Conch, Tragus, Helix 16G 8mm, Implant Grade Hypoallergenic Flatback Stud - FINE4U 1PC ASTM F136 Titanium Broken Heart Piercing Jewelry for Conch, Tragus, Helix 16G 6mm 8mm,Hypoallergenic Flatback Stud --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/642018601-astm-f136-titanium-16g-screw-on-flatback-stud-6mm-8mm](https://www.desertcart.pt/products/642018601-astm-f136-titanium-16g-screw-on-flatback-stud-6mm-8mm) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-16*
