This is a K9 brand carrier bag from America, designed for small to medium-sized dogs, with mesh sides for excellent breathability. The model is plus2, size M. Size details can be found on the manufacturer's website. I purchased this from a previous owner, but it doesn't fit my dog, so I'm selling it. The previous owner used it a few times. I only tried it on once, and there are no noticeable stains. I bought a different size and used it, and it was perfect for outings with my dog. - Brand: K9 SPORT Sack - Color: Gray - Type: Carrier Bag - Features: Allows you to carry your dog on your back - Size: M Please refrain from purchasing if you are concerned about minor details due to home storage.
