Blue anti-lost harness with cushioning, made of nylon and designed for safety. - Color: Blue - Brand: baby coupe - Material: Nylon - Function: Anti-lost harness - Design: Cushioned harness Thank you for viewing. I purchased this because my child didn't want to hold hands, but it improved shortly after, so I hardly used it. The instruction manual is missing. A simple lock is attached to the part that goes on the child's hand.
