Taihaku Oboro kelp is made from Kombu, a type of seaweed that can be eaten as a healthy snack. Craftsmen cut and scrape the kelp one by one to remove the outer black epidermis leaving a pure white kelp. It is so light it will melt in your mouth. This product is gluten free, vegan and zero calories. Which is why it plays such a strong part in the diet of Japanese monks and the Japanese royal family.
