Tiny Tac slip leashes are made from 6mm prusik or climbing accessory cord for strength, light weight, and durability. The loops are hand sewn, then crimped with lightweight aluminum ferrules, and covered with shrink tubing. Just because your fur baby may be tiny, doesn’t mean they can’t have a leash that is supper tough and looks as cool as they do! These are handmade to order. All materials are produced in the US. Secondary variation is for shrink wrap and O-ring color combo.
