Seeknit Koshitsu BOX Interchangeable Circular Needle Tips Set — 10cm/4in

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

The Seeknit Koshitsu interchangeable needle system with 10cm/4in tips is designed for knitters who prefer a shorter, more compact needle length with excellent control for smaller circumference projects.
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 and screw system 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 10cm/4in.
This shorter length is ideal for sleeves, hats, children’s garments, and projects worked on shorter cables, offering precise control without excess needle length.

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.

The S Set covers fine-gauge work, the M Set supports everyday knitting, and the L Set is designed for heavier yarns and larger stitches — all built on the same premium materials and engineering.

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