It is an herbal tea that pursues ease of drinking and deliciousness by adding fruits and flavors while retaining the original flavor and characteristics of herbs. When you want to feel as light as a butterfly fluttering in a flower field. If you add lemon, you can enjoy the change of color from blue to purple. Refreshing lemon scent and a hint of acidity. Since natural raw materials are used, it may not be bright blue. Depending on the quality of the water used for extraction (hardness, etc.), there may be differences in the way the color comes out, but there is no problem with the quality. Caffeine-free (caffeine 0.00%) 10 pieces (tea bags) are individually wrapped. Packs of 30 and 100 are not individually wrapped.
