If you have to choose one tool for knitting, except yarn and needles, I would say choose this one. It has all the necessary measures. For gauge, knittingneedles from 2mm up to 12mm and also a row for crochet-hooks.
The measurement tool is made out of bamboo.
This handy device is specifically designed to help you measure your knitting, ensuring that every row and gauge is the correct length and you're using the correct thickness of needles.
The product is made in China.
