These are Nishiki cloth diaper covers made with high-quality wool, and they're very popular. I've been storing these at home for a while, so I'm offering them at a discounted price. The current version costs around 1,980 yen per cover, and 4 covers would be 7,920 yen. So, if you're okay with the older version, this is a great deal. Wool, a natural material, is gentle on a baby's skin, keeping them cool in the summer and warm in the winter, making it comfortable to wear year-round. * New, unused * Set of 4 * Newborn size (50cm) Cloth diapers, made in Japan, wool, cotton, anonymous shipping, for those who like them.
