Free hands --- It is recommended that every pigeon breeder must have a pigeon product! With it, completely liberate your hands, one person to see the pigeon eye, injection, medication, etc. No longer trouble, very practical!
Split design --- The button uses a split structure, how many times it will not break. The old product button has a one-piece structure and will be broken when used repeatedly.
Unique design---The back, sides, keel and other places are designed with hollowing out for easy appreciation, injection and collar operation.
Environmental protection---It adopts screwless structure, easy to install and use, and will not rust. Can be reused multiple times.
