YEHAM&reg;16.4 Feet 3 Sizes1mm 1.5mm 2mm) Bonsai Training Wire Good quality aluminum wire with a copper coating, anti-corrosion and rust resistant. The wire was easy to cut with regular scissors. It was easy to wrap around your plants and hold them together without damaging them. Due to this wire being lighter it was extremely easy to twist the ends together to hold in place and to untwist when you needed to move it. Great wire for not only training Bonsai but also for tomato plants and can be used for all kinds of different crafts.
