Color: Silver Outer Diameter: 0.35mm x Length (approx.): 30m Outer Diameter: 0.38mm x Length (approx.): 30m Outer Diameter: 0.45mm x Length (approx.): 30m Outer Diameter: 0.5mm x Length (approx.): 25m Outer Diameter: 0.6mm x Length (approx.): 25m This is a durable wire for making and remaking power stone bracelets. It is a stainless steel stranded wire coated with nylon (transparent), which has no elasticity and excellent strength. Because it is made of stainless steel, it is resistant to water and oil stains and does not rust, so you can use your accessories for a long time. For making suncatchers, we generally recommend 0.38mm and 0.45mm. If it becomes heavy, we recommend choosing 0.5mm or 0.6mm. It is more resilient than fishing line, flexible and durable, making it ideal for heavy necklaces and bracelets, and designs that make use of the wire. Because it is elastic, the ends should be treated with crimp beads or ball tips instead of tying them. While it has strong resilience, it can leave marks if bent, so it needs to be handled carefully. #MarineBlue☆ ※ Marine Blue offers other beads, suncatchers, and various handmade craft supplies, so please search for #MarineBlue☆.
