Perfect for marking rows or holding a stitch or stitches off the needles e.g. for knitting a button band. The bulb shape also makes them perfect for use as a stitch marker fitting needles up to approximately 6.5/7mm or US 10.5. Great for crochet too. Unlike standard safety pins these are coil-less so won't snag your yarn. Measure 21mm x 9mm. Black coated finish. Set of twelve packaged in a labelled grip-seal bag. A perfect little multipurpose tool for your knitting bag!
