Instant purchase is OK. Price negotiation is OK. This is a coaster given as a bonus when purchasing items at the cafe during the Ghost and Mrs. Muir Nagoya performance by the Shiki Theatre Company. There are three coasters, and the price is set for one. Please let me know in the comments section which coaster you would like. It is also possible to purchase all three together, in which case the price will be 2500 yen.
