In my opinion these tumblers are the perfect little wine/tea cup set. They are glazed with Tenmoku and Shino (glazes as old as the Song dynasty and the Momoyama period respectively) and fired to cone 10. They hold approximately 8 ounces and when you drink out of them you must sing: “ I just know that something good is gonna happen/ I don’t know when/ but just saying it could even make it happen”
