Clover is well known for its myriad of knitting accessories and notions, and I'm a great fan of them. Clover's Small Point Protectors are you going to stop the sharp end of you knitting needles doing things they shouldn't, like poking through your knitting bag. They'll also prevent your knitting from shooting off your needles when you're out and about travelling. They fit nice and tight on the end of your single pointed needles and are a helpful addition to your kit bag.
They're available in small for needle sizes 2mm to 4.5mm, as well as large for 3.75mm to 6.5mm.
