Seeknit Koshitsu BOX Interchangeable Circular Needle Tips Set — 14cm/5.5in Nordic

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

The Seeknit Koshitsu Nordic interchangeable needle system with 14cm/5.5in tips is designed for knitters who prefer longer needle tips combined with extended cable lengths for comfortable, uninterrupted circular knitting.
This product is offered in three configurations — S Set, M Set, and L Set.
Material, construction, and performance are identical. 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-treated bamboo.

Needle tip length
All needle tips in all sets measure 14cm/5.5in.
This longer Nordic-style tip provides excellent reach and leverage, ideal for sweaters, yokes, colorwork, and projects requiring long cable runs and stable hand positioning.

Material: Koshitsu-treated bamboo
The needle tips are crafted from Japanese moso bamboo enhanced through a specialized heat and pressure treatment. This process:

• increases density and durability;

• improves dimensional stability;

• creates a smooth, refined surface;

• delivers precise stitch control while remaining warm and comfortable in the hands.

Compared to standard bamboo, Koshitsu bamboo feels firmer, more stable, and more controlled.

Smooth joins and rotating cables
The transition between bamboo tips and metal connectors is completely seamless. 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 ideal for knitters who favor longer needle tips and extended cable lengths for garments, colorwork, and large-scale projects.
The S Set supports fine-gauge knitting, the M Set covers everyday work, and the L Set is designed for thicker yarns and bold stitch patterns — all built on the same premium materials and engineering.

Seeknit Koshitsu is a system where length, material, and millimeter all have purpose.
