This Japanese “Cayuca” copper wire (#13 – 2.3 mm) is specially designed for bonsai wiring, an essential step in shaping and structuring the tree. Thanks to its pure copper (99.99%) composition and specific heat treatment, it offers an excellent balance between flexibility and retention.

After application, the wire gradually hardens, allowing it to hold branches in position long-term. It is particularly suitable for conifers and species requiring prolonged support to achieve a lasting shape.

Its darker shade than classic wires allows it to blend visually with the tree, providing a more aesthetic result even after application. Its compact 200 g format is ideal for precise work or for small bonsai enthusiasts.
