This is a 2-way carrier bag that can be used as both a抱っこ (hug) carrier and a backpack carrier. It's a size M, suitable for small dogs weighing 4-6kg. It was purchased new from an authorized retailer for 12,650 yen (tax included). Product Number: 752-29205 It's lightweight at approximately 880g, but the fabric and construction are sturdy, providing stability. The front-facing hug carrier allows you to see your dog, offering peace of mind. The khaki color also makes it suitable for men to carry. The bottom has a fluffy cushion and a removable hardboard, allowing the bag to stand on its own. Removing the board turns it into a soft backpack (see photos 3 and later). I bought it for a puppy, but they grew faster than expected, so it was only used four times. Although it's stated for 4-6kg, it felt a bit cramped when my dog reached 5kg. I bought it this spring, so it's still a current product. You can find more details by searching for the product name. While there were no accidents inside, I've hand-washed it once with an unscented, natural, delicate detergent (no shape distortion) because I thought other dogs' smells might be undesirable. I believe it's in overall good condition. Thank you.
