Asymmetric Circular Needles
23cm (9.5″)

  • “Koshitsu” is a product that has achieved a smoother surface and longer lasting durability through “high temperature, high pressure treatment” and “impregnation of natural plant wax” developed by our company based on our vast experience over 100 years of history.It is characterized by the apparent density of the needles, the glossy surface, and the slippery feel. And above all, it is our original lineup that no other company offers.


  • Our exclusive original 23cm Asymmetric Circular Needles were developed for use with sock yarn, and are available in diameters from 2.00mm to 6.00mm.
  • Asymmetric Circular Needles have a short needle and a long needle. Put the stitches on the short needle and work through with the long needle. Since the moving needle is longer it is easier to hold, making these suited for small circular projects (such as socks).
