These stitch markers are made with genuine Lego sextants. Each listing is for a set of four markers. They have been carefully made to ensure your knitting doesn't snag. The markers will fit needles up to 8mm (US 11), and make a fun addition to your knitting project.Need removable markers? Check out my listings for Crochet Markers, or message me. I'm always happy to change the rings to clasps on request.
