Seeknit Koshitsu Interchangeable Circular Needle Tips Set — 6 cm / 2.4 in

Japanese precision. Hardened bamboo. One tip length, two clearly defined sets.

The Seeknit Koshitsu interchangeable needle system is built around a single, carefully engineered tip length and offered in two distinct configurations — S Set and M Set.
Both sets share the same materials, construction, and performance. The only difference is the range of needle sizes included.

All components are manufactured in Japan by Kinki Amibari Co. using Seeknit’s proprietary Koshitsu bamboo treatment.

Needle tip length
All needle tips in both sets measure 6 cm / 2.4 in.
This compact length offers excellent control and is ideal for circular knitting, including small circumferences and detailed work.

Material: Koshitsu-treated bamboo
The needle tips are made from Japanese moso bamboo enhanced through Seeknit’s proprietary heat and pressure treatment. This process:

• increases density and durability;

• improves dimensional stability;

• creates a smoother, more refined surface;

• provides superior stitch control, especially on smaller sizes.

Koshitsu bamboo feels more precise and composed than standard bamboo while remaining warm and comfortable in the hands.

Smooth joins and rotating cables
The transition between bamboo tips and metal connectors is completely seamless, allowing stitches to glide without snagging. The transparent cables are flexible, memory-free, and feature a rotating joint that prevents twisting during knitting.

Who this system is for
This set is designed for knitters who value precision, durability, and a well-structured interchangeable system. The S Set covers fine-gauge work, while the M Set offers a reliable everyday range — both without excess and without compromise.

Seeknit Koshitsu is a system where every detail has a purpose — from material to millimeter.
