This sweater knitting machine kit is made of ABS and is durable and easy to use. Children can use a children's knitting machine to weave sweaters, bibs, scarves, etc. You can create a flat or round needle in a few seconds through manual crank operation; just thread the yarn into the spindle and then turn the crank to knit your own cool fashion accessories, such as hats, scarves, gloves, socks, leg covers, and clothes. Great for cultivating children's manual abilities, eye and hand coordination, vision, and other skills.
