With your other hand, grip the front of the earring (the stone\/top) and twist anti-clockwise to unscrew. The internally threaded system means it unscrews from the front — not from the back like regular studs. Use the included insertion tool if needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do you put in flat back earrings?\u003c\/strong\u003e\u003cbr\u003e\nInsert the post through your piercing from the back, flat side against your skin. Then screw the top (stone\/decorative end) clockwise onto the post from the front. Every IVY order includes all three bar sizes (4mm, 6mm and 8mm) plus an insertion tool — so you can find your perfect fit and change bars effortlessly at home.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between internally threaded and threadless flat back earrings?\u003c\/strong\u003e\u003cbr\u003e\nInternally threaded means the threading (screw) is inside the post — so nothing rough enters your piercing. Threadless means the top is held in by a slight bend in the pin. Both are body-safe options. IVY uses an internally threaded system, which is the standard preferred by most professional piercers for its security and durability.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre titanium flat back earrings hypoallergenic?\u003c\/strong\u003e\u003cbr\u003e\nYes. ASTM F136 implant grade titanium contains no nickel, no lead, and no alloys that commonly cause reactions. It's the same grade used in surgical implants and is widely considered the safest material for pierced ears — including new piercings and healing cartilage piercings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between flat back earrings and regular studs?\u003c\/strong\u003e\u003cbr\u003e\nRegular studs use a butterfly or push back clasp that can dig into your skin, especially when sleeping. Flat back earrings have a smooth disc that sits flush against your skin — much more comfortable for all-day and overnight wear, and far less likely to snag or irritate.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAre flat back earrings good for cartilage piercings?\u003c\/strong\u003e\u003cbr\u003e\nAbsolutely — they're the preferred choice for helix, tragus, conch and cartilage piercings. The flush back doesn't catch on clothing or pillows, and internally threaded titanium is the standard recommended by professional piercers. We recommend a 3mm CZ stone for cartilage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan you shower and sleep in flat back earrings?\u003c\/strong\u003e\u003cbr\u003e\nYes. Titanium is fully waterproof — safe for showering, swimming, the gym and sleeping. The flat back design is also much more comfortable to sleep in than standard butterfly back studs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does implant grade titanium mean?\u003c\/strong\u003e\u003cbr\u003e\nASTM F136 is a regulated standard of titanium used in medical devices and surgical implants. All IVY flat back earrings are ASTM F136 — not titanium-toned, not titanium-coated. Actual implant grade titanium, throughout.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat gauge are IVY flat back earrings?\u003c\/strong\u003e\u003cbr\u003e\nIVY flat back earrings are 16g (1.2mm) — the standard gauge for most ear piercings including lobes and cartilage. If you had your ears pierced at a professional studio, they are almost certainly 16g or 18g. IVY fits both.\u003c\/p\u003e","brand":"Swiss Hyper","offers":[{"title":"Single \/ 1.5 mm (0.06\")","offer_id":53816447107399,"sku":null,"price":24.0,"currency_code":"CHF","in_stock":true},{"title":"Single \/ 2 mm (0.08\")","offer_id":53816447172935,"sku":null,"price":24.0,"currency_code":"CHF","in_stock":true},{"title":"Single \/ 2.5 mm (0.10\")","offer_id":53816447238471,"sku":null,"price":24.0,"currency_code":"CHF","in_stock":true},{"title":"Single \/ 3 mm (0.12\")","offer_id":53816447304007,"sku":null,"price":24.0,"currency_code":"CHF","in_stock":true},{"title":"Single \/ 4 mm (0.16\")","offer_id":53816447369543,"sku":null,"price":24.0,"currency_code":"CHF","in_stock":true},{"title":"Single \/ 5 mm (0.20\")","offer_id":53816447435079,"sku":null,"price":24.0,"currency_code":"CHF","in_stock":true},{"title":"Pair \/ 1.5 mm (0.06\")","offer_id":53816447140167,"sku":null,"price":40.0,"currency_code":"CHF","in_stock":true},{"title":"Pair \/ 2 mm (0.08\")","offer_id":53816447205703,"sku":null,"price":40.0,"currency_code":"CHF","in_stock":true},{"title":"Pair \/ 2.5 mm (0.10\")","offer_id":53816447271239,"sku":null,"price":40.0,"currency_code":"CHF","in_stock":true},{"title":"Pair \/ 3 mm (0.12\")","offer_id":53816447336775,"sku":null,"price":40.0,"currency_code":"CHF","in_stock":true},{"title":"Pair \/ 4 mm (0.16\")","offer_id":53816447402311,"sku":null,"price":40.0,"currency_code":"CHF","in_stock":true},{"title":"Pair \/ 5 mm (0.20\")","offer_id":53816447467847,"sku":null,"price":40.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0812\/5906\/9767\/files\/1_3c32137b-7adb-4daa-a1cf-9920c9b70e0d.png?v=1769438350","url":"https:\/\/swisshyper.com\/products\/ivy-titanium-flat-back-stud","provider":"Swiss Hyper","version":"1.0","type":"link"}
