Baby mitten 3-piece set. The material is soft, but I don't remember what it is. The plain blue and white mittens are mesh type, which is breathable and prevents heat build-up. Purchased at Nishimatsuya and used only 2-3 times, so there is almost no dirt. I think they can still be used♪ *Washer with baby detergent, but please refrain from purchasing if you are concerned, as it is stored by an amateur. *Returns are not accepted unless there is a valid reason, such as items different from the photos or more dirty than the photos uploaded (photos taken just before shipping in the packaged state, etc.). *Shipping from Okinawa Prefecture, so the expected arrival date may vary slightly. Please understand.
