Thank you for viewing! Silver 0.38mm, 3 rolls I purchased this from an overseas website. I don't remember the length ( ´ᵕ` ;) I bought too much, so I'm putting it up for sale here♪ It's more resilient than fishing line, flexible, and durable, making it ideal for heavy necklaces, bracelets, and designs that utilize wire. It's a stainless steel twisted wire coated with nylon. It's non-stretch and highly durable, and the stainless steel material is resistant to water and oil stains. It's also rust-resistant, so your accessories will last longer. Because it's elastic, the ends should be finished with crimp beads or ball tips instead of tying knots. While it's strong, it can leave marks if bent, so it needs to be handled carefully.
