I purchased 100 grams of "Lemon Balm" from Karis Seijo. I bought it when I was drinking herbal tea every day and have stored it in a cool, dark place with low humidity. It is new and unopened. The expiration date is December 2025. I purchased it for 2592 yen. As you can see in the fifth photo, there are some scratches on the seal. Please refrain from purchasing if you are concerned about this.
