One hand made leather cuff, backed with blue-dyed snake skin. The skin came from a seasnake that died in captivity of natural causes. The rest of the leather is cowhide leather from a scrap-salvage pile.
I've seen a bright green snake here once, it was the only time I'd ever seen such a snake in the wild though and I have no clue what sort of snake it was. Never saw anything like it again. Snakes in general aren't common here but there are rattlesnakes around the badlands.
Depends where you live, but I actually think you might have seen a Blue Racer, they live in Midwestern United States. If it was a Racer, it's good you didn't catch it, they throw huge hissy fits (Hah! Terrible pun) where they writhe, bite and release foul odours. Generally harmless, though.
I just looked at some pictures of them, does look close too, but they're generally dark in appearance it seems. A blue racer in Florida would be weird but people release pets all the time so it could of been one.
