The Addi Click interchangeable system allows you to combine any of ten tip sizes with the three cables provided to create over 500 combinations of circular needles. The set includes:
10 pairs of plated needle tips, in U. S. size 4 to 15
3 flexible blue cords in 24", 32", and 40" lengths
1 connector for combining two cords
No tool is required to join the tips to the cables. You insert the cord into the tip and twist it into place. In addition, two cables can be combined to give you lengths of 24" to 72".
The cords and tips are stored in a specially-designed vinyl case. It holds the tips in place under elastic bands while the cords are stored in an attached pouch. The case folds to a 9" x 6" clutch and is secured with three snaps.
