This is a set of 4 Ryukakusan Throat Refreshing Tablets. Expiration dates: December 2026: 2 bags February 2027: 2 bags They are stored in a place away from high temperatures and humidity, but they are kept at home, so please purchase if you don't mind the details. There is an indoor cat, but it has its own room and does not have access to these items. My husband is a smoker, but he smokes outside. They will be shipped via Yu-Packet Post Mini. If you have any other questions, please feel free to ask in the comments.
