The Key Band-It is a durable, comfortable, stretchy key wristband equipped with a polycarbonate S-Biner MicroLock and a stainless steel split ring to keep keys close at hand and easily accessible. The accordion-style design features latex-free TPR material that slides easily over a hand to be worn around the wrist or arm. The included S-Biner Microlock allows for quick connection to the band or split ring, making it an ideal place to keep keys to which you need frequent access, or for key holding when you need to be hands free.
