Hiya-Hiya steel tips come in either 4" or 5" and equal that length once inserted into the cable. The tips are lightweight, smooth, strong and are made of high quality stainless steel that will stay the same after years of heavy knitting. The screw together connection stays tight and has a seamless join for no snagging or bumps, the stitches will slide right over the connection. The tips are ideal for working with all yarns and will not hurt your finger if you push off with your fingertip when you knit. Both 4 and 5" tips are available in US sizes 2-15 (2.75 mm -10 mm).
