The Shirotake Interchangeable Tips have a smooth surface and a finely buffed tip making it a joy to crochet.

M1.8, M2, and M4 size screws are used for the 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.

Seeknit metal parts are made of brass and nickel-free.
