The Koshitsu Interchangeable Tips have a smooth surface and a finely buffed tip making it easier to pick up your stitches. With a long lasting durability achieved by a high temperature, high pressure treatment and finished off with natural plant wax to create a wonderfully warm and sleek needle.

M1.8, M2, and M4 size screws are used for the needle tips and cords. You can directly connect the needle tip and the cord with screws of the same size:

• M1.8 tip sizes 2.00-3.25mm
• M2 tip sizes 3.50-5.00mm
• M4 tip sizes 5.50-10mm

You can use the converter to reduce the screw size of the needle tip and cords.  Also, you can extend the cord length with the cord joints.
