Use these versatile clips for id tags, (license, microchip #’s, rabies tag, etc.) Easy to move from one collar to another. Use for your Hiking and Hunting companions. Hang on the crate for easy access and quick identification. Hang on your belt loop if you don’t like them dangling on the collar. 

Sturdy but lightweight. Strong side release buckles.  I use these on my dogs when hiking and they hang on my crates in the truck when not in use.
