- Product Name: Suru Suru Tea - Contents: Tea leaves (tea bag) - Features: Tastes like roasted green tea. Helps you go! Thank you for viewing. I have a large stock because I signed up for an annual course. Due to my job, I don't get to go to the restroom very often, so I'm limiting how much I drink. The expiration date is (2027.4.27), so I'd like to sell it to someone who wants to try it.
