These metal, locking stitch markers are slim and tidy. They work for either knitting or crochet, as well as to snag dropped stitches, mark the front/back of a garment, or identify other things as you work.
Being lockable, these work for knitting or crochet. They easily fit on knitting needles up to size US 10.75/7mm. (The bulb is about 10mm across, but you need plenty of room for it to slide easily.)
Please note that (except for all-white) each package will have a unique, random assortment of colors and will vary from what is pictured.
