These silicone point protectors from Clover are a great tool to not only protect the points of your knitting needles or embroidery scissors from chipping or bending, but they also keep your knitting from falling off your needles while it's not being worked on, and it keeps your scissors from poking through any bag or notions pouch you might have them in!
They come in two sizes - the smaller green ones are best for small embroidery scissors and US knitting needle sizes 0-6, and the larger purple are best for larger scissors and US knitting needle sizes 7 and up, and they come in sets of two.
