Multi-function:Use for sprains, swelling and soreness;It works well on ankle, wrist, finger, toe, elbow and knee. Also safe for pets. Worth the amount:There are several fashion and basic colors and 12 rolls for each pack. You can use it for a very long time with one buy. Strong Self-adhesive:Made of cohesive elastic latex free non-woven. Unlike non-adhesive bandages, self-adherent tape does not require clips and pins to stay in place.
