This is a Snoopy cooling mat, a special bonus from the Japanese magazine "Hajimete no Hiyoko Club" (First-Time Hiyoko Club) 2024 Spring/Summer issue. I opened it intending to use it and washed it with baby detergent, but I ended up using something else, so it has been stored at home unused. It will be folded for shipping. Please understand. From the official website: [Product Features] * The front uses a cool-touch fabric that feels cool to the touch, and the back is soft pile fabric. * If you lie down on the mat during naptime, it's cool and comfortable! You can also use it as a pillow when breastfeeding. * Place the mat on the stroller and secure it with the strings, and you can enjoy outings on hot days. The key is to put the mat between the back to absorb sweat! It can also be used in car seats and baby carriers. * Hand washing at home is also OK! [Product Specifications] Approximately 40cm long x 28cm wide, with strings at the four corners for securing.
