Chokers/collars made with large scales, 2 scales wide.

The on is in stainless steel with the standard hook clasp I've been using for a while.
The other is in green anodized aluminum with a heavier-duty lobster clasp that I kind of like.

Something like this would be $25, and add $1.50 on for the lobster clasp.

Currently I'm kind of limited in number of colors for these scales, but I'm getting a few more in pretty soon hopefully.
