This is a THERMOS insulated cooler bag! When I upload photos to Mercari, the space-time continuum seems to warp, but the third photo is what the fabric actually looks like. It has a cute Miffy design, but I haven't used it in a long time, so I'm selling it. Approximate size: 26 x 17 x 17 cm It shows signs of use, with some stains on the bottom and inside. Please check the photos and consider purchasing if you understand. Feel free to comment if you have any questions!
