Stretchable and Adjustable: Not only is the stainless steel rope stretchable, longest :1.5m,but the size of the bracelet can also be adjusted freely (up to 14cm), so there is no need to worry about whether the size is appropriate.Upgraded Key Lock: Our upgraded toddler leash uses a key lock, and the key is on the adult side, so it is impossible for children to unlock the bracelet, which is safer and more reliable than the old one that uses hook and loop closure.Comfortable and Breathable: Our baby leash is very comfortable to wear as it is embedded with soft breathable cushioned cotton. The connection between the rope and the bracelet can be rotated 360 degrees to prevent the rope from tangling.Strong and Durable: The rope is made of cut-resistant stainless steel and is wrapped in thickened PU material, which is not easy to cut. The connection between the bracelet and the rope is connected by a metal joint, which is not easy to separate.Anti-lost and Play Safely: Our child leash allows children to move independently within the sight of parents, especially in crowded places outdoors like parks, small shopping malls and amusement parks, to prevent children from getting lost.
