Hiya-Hiya bamboo tips come in either 4" or 5" and equal that length once inserted into the cable. The tips are smooth, strong and have a resin finish that will stay the same after years of heavy knitting. The tips have the perfect point to not split stitches but yet easily glide into twisted or complicated maneuvers. They warm in you hands and are ideal for all yarns. The 4" tips are available in US sizes 2-8 and the 5" tips are available in US sizes 2-15.
