I believe it was a Gundam manhole cover coaster that you could get by purchasing a product worth 500 yen or more in Wakkanai City and taking the receipt to the city hall. There are 3 sets of the Gundam manhole cover coaster and a Dom manhole cover coaster, so they can be used for gatherings, for preservation, and for display purposes ( ^_-)-☆ Please refrain from price reductions. Available for immediate purchase.
