3mm, Anodized Aluminium wire, Made in Japan

To create beautiful bends in a bonsai tree, consider using suitable wire and winding it around branches or even the trunk of the tree. This can be done by the bonsai artist at any time, and when the wire is removed some weeks or even months later, the shaped area will remain in that form. Keep in mind that the best time to wire deciduous trees is in late spring through autumn, while evergreens such as pines and junipers are better wired in winter. For evergreens, annealed copper wire is recommended for its superior holding power. However, for deciduous trees, anodized aluminium wire is the material of choice. Other uses for wire include guy wiring, securing drainage mesh, and securing freshly repotted trees into their pots.
