Making bracelets inevitably involves some failures. You'll need a lot of Ope-lon rubber. I purchase 10N spools of Ope-lon rubber from Hinryo. I don't wind them myself. A small amount of trial silicone rubber is included. The bead threading wire is also easy to use. Fine wire that can pass through small hole diameters is also included. ◆ Product Contents 2 x 10m Ope-lon rubber, 10 wires, Instruction manual ① 2 x 10M spools of white Ope-lon 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 damaged easily. There are holes that only 0.3mm wire 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 Ope-lon rubber. A Hinryo bracelet making instruction manual is included. ★ About Crystal Thread Width: 0.8mm For bracelets 100% Polyurethane ※ You might understand better by watching videos, such as those on YouTube, that show how to make bracelets. The 100-yen shop's Ope-lon rubber is also quite good. The knots can be itchy against the skin. It's not a problem if they're inside the beads, but they don't sell wire, so the 10 wires currently on sale are a great deal. Please try making your own wonderful, original bracelet! ^_^
