Rare Babymetal dog collar. A friend bought it for their chihuahua but it was too big. They gave it to us to use for our cats but it was also too big for them. So it was tried on 3 pets but never worn for more than a minute. The size is medium. The bandana is attached by velcro so it can be removed. It was originally sold in a limited edition pet & baby themed merch release back in 2020 for only a few months. I've only found around 3 listings in different sizes on ebay and they want $40-$90.
