The Nite Ize Gear Tie ProPack is a bulk pack of reusable rubber twist ties for tackling many wrapping, hanging and bundling jobs at once. Each Gear Tie has a strong bendable wire core and a tough, grippy rubber shell that holds firmly without scratching or marking. Wrap and twist to secure, then untwist and reuse hundreds of times. You can also loop one end, thread another tie through and twist to link several ties into a longer one. The 6-inch (about 15 cm) size suits cables, chargers, appliance cords and similar medium-sized items. Gear Ties are waterproof for fresh and salt water, UV resistant, suitable for indoor and outdoor use and made in the USA. This pack holds 12 black ties.
