This is a set of two replacement covers for the Tamago Mat Oくるみ Sleep, suitable for newborns up to the time they can hold their heads up. Please note that this listing is for the covers only; the inner core is not included!! This is a limited-edition Year of the Snake design, in a soft, light green/blue color. Purchased around May 2025 and used for about two months. My child didn't like being swaddled, and would struggle when the zipper was closed, so there is some looseness in the fabric, but it is still in usable condition. This item has been used by a baby. Please be aware that there is some wear and tear, such as pilling, so please consider this before purchasing. The towel fabric is soft and comfortable.
