Clover's Jumbo Point Protectors (S) are great at protecting your knitting as well as your knitting bag. The rubber ends sit tightly on each of your needles, which is handy as it stops your needles piercing your bag. They're also good at preventing your work from whizzing off your needles. Super convenient to have as part of your accessory collection.
They're available in two jumbo sizes; small covers needle sizes 8mm (US11) to 10mm (US15), with the large taking care of needle sizes 12.75mm to 15mm (US19).
