These beautiful needles are made of Moso bamboo which is the strongest bamboo species.
Sizes 2mm - 3mm have the same memory free cable as the GhiaoGoo Red Stainless Steel circulars.
Sizes 3.25mm and larger have a nickel-plated, copper join that is glued and crimped to guarantee no separation.
The joins are fantastic, the nylon cable is pliable and the tips swivel freely!
Needle size is permanently laser imprinted on each circular tip for ease of selection. All around this is the perfect tool for small round tubular knitting such as socks, baby items, sleeves or whatever.
