Showa-era retro, durable water pillow made of natural rubber. The rubber part is stamped with DUNLOP. You can use it when you have a fever, for a good night's sleep in the summer, or in the coming season when the flu is prevalent. It's in beautiful condition as it has hardly been used, but please consider purchasing only if you understand that it has been stored at home for a long time. ✦ Due to shipping costs, it will be sent without the box. The main body will be folded for shipping. If you want the box, it will be an additional 500 yen. Please comment.
