Clover is well known for its myriad of knitting accessories and notions, and I'm a great fan of them. Clover's Quick Locking Stitch Marker Set furnishes you a plentiful supply of undulating stitch markers in several striking colours. They can be used in both the closed and open position and are supplied in three different sizes; small, medium and large. The rippled design prevents stretching of your stitches. It's a great little design from our friends at Clover.
