I love buying things for my dog, and now I have too much, so I'm decluttering! (=^ェ^=) This is a Petio product. Size: SS. I bought a collar in case the harness came off, but I never used it. This item has only been tried on. Shipping will be via Mercari. I use recycled packaging materials. Thank you for your understanding. I'm also selling other dog clothes, so please take a look! I don't smoke, but I have a white dog. I will thoroughly use a lint roller before shipping, but I apologize if any dog hair remains. Thank you for your understanding.
