Set of 5 stitch markers for knitting. Can also be used as row markers. The rings have an outer diameter of approximately 1.6cm and an inner diameter of approximately 1.3cm. I think they can be used with thick knitting needles. :: Some materials are different from the previously listed product. Size: Approximately 6.0cm - 6.3cm :: Please check the size image. I have made them carefully so that the yarn does not get caught on the jump rings, etc., but if there is any bending, I would appreciate it if you could adjust it. Please check the last image if you wish to purchase multiple items and have them shipped together. Please note that discounts and combined shipping after purchase are not supported by the system. They will be settled and shipped separately. The charms used are mainly made overseas. If you are looking for a perfect product, please refrain from purchasing. #KnittingTools #NeedleCap #StitchMarkers #RowMarkers #StitchMarker #Crochet #Knitting #AfghanStitch #LaceKnitting #Yarn
