This delicate Spiral Curb Chain measures only 1mm. Made from solid, naturally hypoallergenic brass and electro-plated in Gunmetal. It is perfect for creating tassels, with its twirling movement reflects light and enhances the sparkle.. The chain links are still large enough where you can fit a 3mm 22 gauge jump ring through them or a thin gauge wire. Ideal for necklaces, bracelets and anklets or use shorter lengths to make stylish earrings. Links are soldered for extra strength.
