she does beautiful work. I just got a satin tag colar from her for my IG - which are notorious for sensitive necks.

I'd tried several collars, and Tari was bothered by all of them, prior to this one. It isn't break away, but she could pull out of it if needed, and it has nothing hanging from it to get caught on. A little pricey, but should last forever.
