Making bracelets inevitably involves some failures. You'll need a lot of Opelet rubber. I purchase 10N spools of Opelet rubber from Hinryo. I don't wind them myself. A small amount of test silicone rubber is included. The bead threading wires are also easy to use. Fine wires that can pass through small hole diameters are also included. ◆ Product Contents 2 x 10m spools of Opelet rubber, 10 wires, instruction manual ① 2 x 10M spools of white Opelet rubber (crystal thread) ② 10 wires (costs 10 yen per wire) Randomly selected from 0.3mm to 0.38mm. ③ An instruction manual with bracelet repair and making instructions is included. The making method is the same for double or quadruple threading. Important ※ Shipped via mini-letter (simple packaging) Bead threading wires can get caught and break easily. There are holes that only 0.3mm wires can pass through. It's better to have a lot of them. Also, they are often lost when the number decreases. You'll lose them quickly if you don't store them in a bag like this. The wires are wrapped in the instruction manual. Please rest assured. ● Hinryo Opelet rubber. Includes Hinryo's bracelet making instructions. ★ About Crystal Thread Width: 0.8mm For bracelets 100% Polyurethane ※ You may find it easier to understand by watching videos, such as those on YouTube, that show how to make bracelets. The 100-yen shop's Opelet rubber is also quite good, but it can become tight when you tie it tightly to make a bracelet. Just be careful about that. Wires are not sold separately, so the 10 wires currently on sale are a great deal. Please try making your own wonderful original bracelet ^_^
