Since there are shipping costs, I cannot lower the price (^^) This is a pet carrier bag. It has a lot of mesh, so it was comfortable to travel in even in the summer. For Shinkansen (bullet train), trains, and car travel. If you purchase it together with two other pet slings and pet backpacks, it's 4000 yen for all three. Both were used by a 2kg dog. Please comment if you're interested (^^) [Size, Reference Weight] 40 x 22 x 23cm, body 1.2kg I think it's for small dogs. I used it for a 2kg dog. The material is probably PVC. Used for Shinkansen (bullet train) and hotel travel. I think I used it for travel about 10 times. It's well-made, so the dog was able to travel stably. There are scratches on the handle. I don't remember if it came with a shoulder strap when I bought it, but I will include a shoulder strap I had at home. You can also replace it with a shoulder strap you have at home. I have wiped it clean and disinfected it. Boston carry bag Carry bag Boston Mesh, breathable, airy For pets, summer, dogs, beloved dogs, dog supplies, outings, car travel, travel, moving
