“Smart dog owners carry leashes wound on spring reels. The leashes encased in Tenite are styled in lustrous colors to match almost any costume. By simply pressing a small switch on the handle, the dog may be controlled at any desired distance. Tenite will withstand rough handling without denting or chipping.”
