I received this about three years ago! It's a new, unused item, but the outer box has yellowed, although it wasn't exposed to direct sunlight. [Seller] Isshindo Honpo Co., Ltd. [Contents] Red and Blue, 1 sheet each (2 applications) 22mL x 2 packets Of course, the contents are new and unused, but if you are concerned about the yellowing of the outer box, please refrain from purchasing. Please refer to photo 9 for an image of the mask in use, and photo 6 for detailed ingredients. Please be aware of potential allergies.
