Review on ChiaoGoo Needle Tips 4 inch (10cm) US 6 (4mm) 2504-6 - Spin Interchangeable Set: Reliable, High-Quality Craftsmanship for Precise Knitting by Carol Miller

I love these needles. This is a spare pair of needle tips for the kit where I broke the needle. The kit is one of my most prized knitting tools. They don't break on their own but if helped as I step on them it's great to be able to replace just a single pair of needles that I broke. Some of the descriptions of ChiaoGoo replacement needles confused me and I wasn't sure if I was buying the right needles, but I did. The needles are 4.75 inches from the tip to the point where the screw starts.
