Thank you for viewing! "Yakuzen Enzyme Rice" for boosting immunity Anti-aging recipes taught by a doctor Written by Yoko Uchiyama, Director of Yoko Clinic I am selling this after reading it once. It's very helpful, with monthly yakuzen ingredients and recipes. As you can see in photos 3 and 4, there are small stains on the front and back. Other than that, it's in clean condition, including the inside. Please consider this as a used item.
