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 not stretchy and has excellent strength. Because it's stainless steel, it's resistant to water and oil stains, and it doesn't rust, so you can use your accessories for a long time. Because it's elastic, you should use crimp beads or ball tips instead of tying the ends. While it's strong, it can leave marks if bent, so you need to handle it carefully.
