This delicate Spiral Curb Chain measures only 1mm. Made from solid, naturally hypoallergenic brass and electro-plated in Antique Copper. 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.
