cable needles

Blunt ended cabling needles for knitting. V2 is 6.5mm diameter, V4 is 5.5mm diameter. I would recommend either a very fine print setting or using your preferred method for creating a smooth surface (acetone, nail polish, etc) before using it with yarn so that the surface doesn't catch on the fibers.
