I guess most of you guys have seen one of these, but just in case, here it is.

I wear one of these on my Highland Regiment issue Tam-O-shanter on a daily basis.

I almost never found 'em, but I stumbled onto the site again today. It's a really nice "clan badge" (for all of us McPuller clan boys), and I get a lot of complements on it. Occassionally I wear it on a balmoral, but I usually wear the TOS whether kilted or not.

And the cost is pretty reasonable, too.
