Aoba's My Pillow Neo Plus (Mint Green). Includes a cover. This pillow is used behind the neck when using Ohinamaki. It supports the neck to maintain the C-curve of a newborn. I bought it to prevent flat head syndrome, but my child didn't like it, so I didn't end up using it. It has been stored at home. It has been used only a couple of times, so it's almost new. However, it has been handled by a person once, so I would appreciate it if you would consider purchasing it only if you understand this.
