Seeknit Koshitsu Interchangeable Circular Needle Tips Set — 5cm/2in
Japanese precision. Hardened bamboo. One tip length, three clearly defined sets.
The Seeknit Koshitsu interchangeable needle system with 5cm/2in tips is designed for knitters who prefer a full-length, traditional needle feel with maximum stability and control. 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 5cm/2in. This classic length provides excellent leverage, a familiar straight-needle grip, and superior hand support, making it ideal for garment knitting and long, uninterrupted sessions.
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, and 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.
