This is a souvenir I received after a sand bath. I think it's either buckwheat kernels, sansho pepper, or some other spice, but I'm not sure because I don't know much about it. For those who can use it. New, unopened, 30g. [Product Condition] New, unused [Color] Brown系 (Brown-toned) [Contents] 30g (estimated) Thank you. Tea Spice
