The Tulip Knitting Needle Set features 11 pairs of interchangeable bamboo knitting needles between sizes 3.25 mm (US 3) and 9 mm (US 13). Made from lacquered bamboo, these needles allow the yarn to slide more smoothly while you knit. Their design uses a unique cable join system that simplifies tightening and unscrewing needles without having to use any tools. The smooth rotary cable join prevents yarn from getting caught and twisted. Included in the set are 6 stoppers that go onto the ends of the cable, allowing you to switch out the needles for a different project. For knitting on the go, the set comes with a compact carrying case.
