This retractable zipper accessory is a practical complement for ID card sleeves and key accessories. It is widely used in factory nameplates, corporate employee badges, campus student cards, access cards, exhibition participation tickets, and key storage, among other scenarios. It is highly practical and an excellent item for office and daily use.
 
The product casing is made from high-quality ABS plastic molded integrally. The surface is matte and fine, durable, resistant to drops and wear, and does not turn white or crack over long-term use. It features a high-elasticity spiral spring inside, providing smooth and powerful expansion and contraction. After being stretched, it can automatically and quickly return to its original state, and remains stable even after repeated stretching, without any sticking, looseness, or inability to return.
 
The stretch rope is made of high-strength nylon wire rope, offering strong flexibility and resistance to stretching; it does not easily break strands and can be stretched freely for use. Card scanning for retrieval does not require removing the ID completely, making the operation convenient and hassle-free. Both ends are equipped with zinc alloy lobster clamps and metal key rings. The lobster clamps can rotate freely at 360°, effectively preventing the rope from getting entangled or knotted. The clamps close tightly, making the attachment and removal of accessories simple and easy. The metal key ring engages firmly, ensuring that keys and small items do not fall off easily.
 
A user-friendly design with dual interfaces: one side features a lobster clasp that can be attached to a belt, backpack, or strap, while the other side has a key ring that can connect to ID card sleeves or keys, enabling multiple uses. The overall size is compact and lightweight, making it easy to carry without adding bulk or burden to the wear.
 
Support customized printing, allowing business logos and text patterns to be printed on the zipper cover surface. Suitable for corporate purchases, event gifts, and bulk custom gifts at trade shows. It is ideal for both bulk corporate orders and personal daily use, eliminating the worry of lost IDs or keys.
