Reflective Design: This safety leash incorporates a built-in reflective film that provides strong reflections under light sources, acting as a warning and ensuring your child's safety in the dark. High Security: Equipped with a safety lock requiring a key on the parent's wristband to unlock, preventing the child from releasing themselves – for safer travels. Comfortable: Features a built-in ventilated sponge layer and a soft, widened pad, reducing strain on the hand and protecting against scratches and sweat. High-Quality Materials: Made from thick, one-piece steel wire, this leash offers excellent elasticity, resists deformation under tension, and is strong and durable. Rotating Design: The metal head of this safety leash rotates 360 degrees. Unlike traditional safety leashes, it allows for free and flexible movement, keeping your child safe without feeling restricted.
