【Not for Sale】Sakurajima Shochu Rock Glass with Cherry Blossom Pattern and Temperature Change Feature, Sweet Potato Shochu

This is a novelty glass rock glass that came with the purchase of an imo shochu over 20 years ago.
When cold, the cherry blossoms are a full bloom pink, but
when hot water is added, they change to white cherry blossoms ☆
I believe this is an item that can no longer be obtained.
It's not just for those who like rocks or watered-down drinks,
but it's also a fun glass for those who don't drink alcohol.
I only used it once or twice.
