Retractile / Dog Chain

Retractile
Retractile

Retractile is a new dog chain that could be retractile. Rope is hidden in the back of the collar, which is similar to the structure of the tape. Rope could be retractile according to the dog’s running distance and pulling power. While getting home, just need to release the handle and the rope could retracts automatically. This is very clean and neatly.
