Yes, it is 3/8 wide by 7-10 inches. I had the one in black. We mailed it to Baker. Baker has, um, not outgrown that yet. The snap part is more like a cat collar and it breaks away by popping off like a safety cat collar. But if you clip the 2 D rings you can avoid the breakaway. The bigger ones have a quick clip AND a section with a breakway portion that is rather interesting how it fastens and pops.
Oh, I am wrong, the next ones up are 3/4" and 1 inch". I went with the 3/4 inch because they didn't have 1/2 inch (which is what I would prefer).
Cubby's is 10-14" and Shay's is 14-20. Shay's is close to fully extended. Cubby's is about half way. I think the 3/4" is a little thick, but I will trade some squished fur for safety at least until we no longer crate at night.
I may consider once he is full grown getting Cubby a rhinestone, velvet, or sparkler collar and have the lady build in the elastic stretch that she can add as a safety feature. I don't want to do this til he is full grown though.
