Gray plastic carrier bag with good ventilation. Used about 5 times for a dog. There are some scratches on the bottom. Please check the photos from the 10th image onwards. I am selling it because my dog has exceeded 4 kg and outgrown the size. When packing, I will disassemble the black and gray parts and stack them.
