These are by far my go-to Interchangeable Needles. I love them.
The join between tips and cable is always smooth and reliable. ChiaoGoo exist solely for engineering the best needles, and it really shows.
Crafted from surgical grade Stainless Steel, these needles are just the perfect amount of point that's neither too severe or so long that it affects your gauge. ChiaoGoo have really mastered these tips.
They are tightened onto ChiaoGoo Cables by way of a cable key through a key hole. The key hole is also great for adding lifelines into your work.
Sizes are permanently laser imprinted, so no issues with unidentifiable needles.
