Thank you for viewing. This is a set of 17 packets of Ryukyu Shugo Densetsu, said to be effective for hangovers. The expiration date is October 2027 for all packets. I originally purchased several 6-packet packs on Amazon, but I stopped drinking, so I am selling the remaining 17 packets. Although it has already been opened and partially peeled, I will also include the large bag that it was sold in as a 6-packet pack, so you can see how to use it and the ingredient list.
