Brass-Coated Aluminum Wire 1 mm - 500 g by Crespi Bonsai

To shape a bonsai into the desired form, wire is applied. Given the typically lengthy process, the wire remains on the plant for several months. Therefore, it's crucial to use bonsai-specific wire, like aluminum with a copper coating, to avoid damaging the bark of branches and trunk. This wire offers the benefits of aluminum, such as flexibility, ease of use, while the copper coating eliminates the unsightly appearance of aluminum. It doesn't rust or stain the bark. For effective wrapping, use a wire with a thickness equal to one-third of the branch or trunk's thickness.
