2.5mm, Anodized aluminium wire

Anodized aluminium wire is the preferred choice for shaping deciduous trees, while the best time to wire evergreens such as pines and junipers is during winter. By strategically wrapping wire around branches, a bonsai artist can achieve desired bends and curves, which will remain even after the wire is removed weeks or months later. Other uses for wire include guy wiring to anchor branches, fixing drainage mesh, and securing freshly repotted trees into their pots.
