When I'm lookin' for new critter stuff...DOGS rule! I mean...don't get me wrong. I love all animals...but I REALLY love dogs! So I was happy to find this cutie! This is hematite black stamped brass with a "hollow" or "concave" back. Our photo shows front and back (dog on the right shows the back view). He measures about 17x15mm and has a little loop at the top for stringing. FOUR (4) charms per set.
