Orange plastic hot water bottle Includes a storage bag (handmade, sewn with a sewing machine) Safety certification mark S-0029 Size: Approximately 31cm x 23cm This is the type that you fill with hot water. *Because it's a bit old, the plastic is thicker and the construction is more solid than recent hot water bottles. Image 2: There are two small black marks inside, but there doesn't seem to be anything else visible. The inside has been thoroughly dried, so I don't think there's any mold. This is a used item that has been stored at home for a long time, but it hasn't been used very often and is in relatively good condition. The price includes shipping, so if you are willing to accept this price, please consider purchasing. Thank you for looking.
