This tag arrived quickly and is very nice. The metal is extremely tough; I tried to bend it slightly so it would better follow the curves of my little girl's neck, and it wouldn't give AT ALL. While I do think it's too big for my 9.4 lbs pup, I'm not going to detract from the rating for it. However, I did take off a star because the corners are ridiculously pointy and sharp. When you press with your fingertip, it really does feel like a little more pressure is going to cause a puncture.
