The HiyaHiya steel interchangeable needle sets are divided by size. The small set includes 4" steel needle tips in sizes US 2-8. The large set includes 4" steel tips in sizes US 9-15. Both sets come with 4 cables in lengths 16", 24", 32", and 40". A pair of needle grippers for tightening the connection comes with each set. The cloth cases have colorful brocade outer fabric and black cotton linings.

To connect the tips to the cables, you insert the screw tip on a needle into the connector on the cable and turn. Needle grippers are provided so that you can grasp the needle connections and tighten securely.

Each case unfolds to reveal the pairs of needle tips stored in their pockets. The cables are kept in a zippered pocket on the back of the case. A zippered pocket inside the case can be used to hold stitch markers, cable needles, or other small tools. The case folds to a compact 7" square and ties closed with fabric ties through a fabric loop.
