Wazakura Annealed Copper Bonsai Training Wire, 2.0mm (Japan)

Copper holds a bent shape more firmly than aluminium and is generally preferred for conifers (junipers, pines) where a stronger hold matters, but it's harder to apply and remove without marking the bark than aluminium — better suited to someone with some wiring experience than a first-time buyer.
