This is a rare set of drinking cups for a game. It consists of three cups, large, medium, and small, that nest inside each other. You play the game by rolling a small die. The die has markings for "issho" (1.8 liters), "gogo" (0.9 liters), "igo" (0.18 liters), "rest," "uta" (song), and "?", making it full of fun. It's miniature size and cute. With its unique design, it will liven up any drinking occasion. Perfect for those who love sake or for collectors. Due to shipping costs, the green outer box will not be included. If you would like it, we can include it for an additional shipping fee, so please inquire. Thank you for looking. #Masu (square sake cup)#Kasanemasu (stacking masu)#Matryoshka#Minimasu (mini masu)#Yukyohai (drinking game cup)
