Knit Pro Cables are flexible and attach to IC tips smoothly. I find that stitches glide easily along the needles and onto the cables. Once tightened with the special key, the cables stay connected - there is no mid-knit detach emergency.
Knit Pro cables are now colour coded so you can easily tell which length you are working with. These cables are great.
Included with the cable is the locking key and two end caps which can hold your stitches on the cable while you use the tips for another project.
