200 PCS Earring Backs,Metal Butterfly Design,with Storage Box,Alloy Back Clip,Suitable for All Kinds of Earrings,for Sports,Fitness,Outdoor Activities and Parties(Silver + Gold)

MATCH YOUR EARRINGS WITH TWO COLOURS：Wearing silver studs? Grab a silver back. Gold hoops? Take a gold back. This set gives you 100 silver and 100 gold butterfly backs – so you never have a mismatched metal peeking out from behind your earrings. Looks seamless from every angle. ADJUSTABLE TENSION FOR COMFORT：Earring posts come in different thicknesses. Squeeze the butterfly wings closer for a tight grip on thin posts, or leave them slightly open for thicker ones. A custom fit every time – no pinching, no slipping. STAYS LOCKED DURING ACTIVE DAYS：From your morning commute to an evening out, these metal backs stay locked. The spring‑tight wings grip your post securely through ordinary movement – walking, laughing, even dancing. No constant checking. No mid‑day surprises. 200 PIECES FOR SHARING & SPARES：One back falls off at the gym. Another gets borrowed and never returned. With 200 pieces, you can stash a handful in your travel bag, keep a few in your desk drawer, and still have a full box at home. Generous enough to share without running out. REFRESH OLD EARRINGS WITH FRESH GRIP：Metal butterfly backs don’t wear out quickly, but after years they can loosen. When that happens, a fresh back makes your favourite earrings feel secure again. With 200 pieces, you can replace every tired back on every pair you own – and still have dozens left.
