Seeknit Koshitsu Interchangeable Circular Needle Set L 12.5cm
The Seeknit Koshitsu Interchangeable Circular Needle Set L 12.5cm is a versatile bamboo knitting needle system designed for larger needle sizes and a wide variety of circular knitting projects. The longer needle tips provide additional hand support and are particularly suited to knitters who prefer a more traditional needle length when working on garments and larger projects.
Developed by the Japanese company Kinki Amibari, the Koshitsu range undergoes a specialised high-pressure and heat treatment that enhances the natural strength and resilience of bamboo. Each needle tip is then polished with natural plant wax, creating a smooth, warm surface that allows yarn to glide effortlessly while helping maintain even, consistent tension.
This treatment also helps protect the bamboo from external influences, reducing the risk of warping and increasing durability over time. The result is a knitting needle that feels wonderfully smooth in the hand while retaining the natural warmth and character of bamboo.
The 12.5cm needle tips are paired with the M4 thread system, making this set suitable for larger needle sizes. With interchangeable cables, connectors, and end stoppers included, the set can be adapted to suit a wide range of knitting projects.
