XXS Size Pet Safety Collar - Brand: Recera - Size: XXS - Type: Pet Collar Thank you for viewing. This is a collar used for post-operative care for pets. I purchased it at the hospital last month, but I didn't end up using or opening it, so I'm selling it. It is a new, unused item. I bought it for a kitten (6 months old). This collar is secured with Velcro. I was told to use tape if it's still too big. The original price was ¥1450, I believe.
