  2. Hello, I did not see any warning on the product page that this item has a short shelf life. Had I known this buffer would expire in 2 months, I would have ordered at a later date. Can the people in charge of website improvements add a warning?

    1 답변

    1. This product has a tested expiration date of one year.
