Price not negotiable. Miffy 2-way Soft Cooling Mat The "Miffy 2-way Soft Cooling Mat" is a mat that can be used from the newborn period, with a cooling material on the surface and soft pile fabric on the back. It's useful as a mat for naptime, and also for heat対策 in strollers and baby carriers when it gets warmer and you start going out. This mat is perfect for low-month-old babies. You can use the pile fabric side up in the colder seasons, and the cooling contact material side up when it gets warmer, allowing for long-term use. The simple gray and white design can be used not only at home but also when you're out and about. It's washable at home, so it's always clean. Although it is unopened, I will open only the cardboard box for shipping due to size restrictions. Please refrain from purchasing if you are concerned about storage at home. I am also selling this item elsewhere, so there is a possibility that it will be deleted suddenly.
