This is a new kind to walk with your dog.
With this wrist leash you have your both hand free!
You can chose to keep it on your wrist or to move it to your belt.
An internal mechanism allows the leash to extend and retract as a normal retractable dog leash, but the wire inside is really lightweight and strong and you can chose to keep short wire or long wire for the happiness of your dog.
This is a project.
