Instant purchase is welcome. I bought this because I was concerned about my child's head shape, but my child didn't like it and wouldn't use it, so I opened it but never used it and stored it in a dark place. I purchased it for 2980 yen. See the third photo. There is a small stain on the back of the cover. Please understand this before purchasing.
