Cool holder ! (And a cute puppy on the PB link too....)
I think an in-line holder would also be cool - it could strap to the belt horizontally for a much smaller carry profile. I carry my multi-tool and Streamlight PT2L in horizontal-carry, and would snap up a 2xCR123 horizontal-carry battery holder in a heartbeat !
Is that made by vacuumforming ? Once again, it looks great. :goodjob:
