I completely forgot I had this, having purchased it and stored it in a dark place, and since I don't plan to use it in the future, I'm putting it up for sale. Expiration date: February 2020 The box shows signs of aging. The oil looks normal, but since it hasn't been opened, I can't guarantee the quality. Please understand this before purchasing. Thank you. Retail price: 4,510 yen Individual sales are also possible. #White Birch #WELEDA
