Earring Backs 500 Pcs Gold&Silver, 4 Styles Metal for Studs

4 STYLES, 2 COLOURS, 500 PIECES – 150 silver + 150 gold butterfly backs (4.3x6mm) for a flat, invisible fit behind small studs. 100 silver + 100 gold disc backs (10.5x5.5mm) for a wider grip on hoops and heavier earrings. One mega set covers every jewellery need. TWO MATERIALS FOR OPTIMAL PERFORMANCE – Butterfly backs are made from durable alloy for a secure, long-lasting grip. Disc backs are crafted from lightweight plastic胶片 for comfortable all-day wear. The combination gives you the best of both — strength when you need it, comfort when you want it. 500 PIECES – BULK QUANTITY FOR PROFESSIONAL USE – With 500 pieces in one set, this is the ideal choice for small boutiques, craft fair vendors, party planners, and DIY studios. No more frequent reordering — stock up once and have enough earring backs to cover weeks or months of projects, events, and customer orders. Perfect for those who use earring backs in volume. LIGHTWEIGHT COMFORT, SECURE GRIP – Both styles are designed to stay put without weighing down your ears. Butterfly wings close firmly around the post; disc backs provide wide, stable support. Whether at a party, gym, or outdoor adventure, your earrings stay secure. VERSATILE FOR MULTIPLE PIERCINGS & PROJECTS – Not just for earrings. These backs fit lip studs, labrets, and various body jewellery. The 4-style combo with gold and silver options ensures you always have the right colour and fit for every piercing — and enough quantity for crafting, reselling, or sharing with fellow makers.
