ROUNDLAB Birch Juice Moisturizing Serum ROUNDLAB Birch Juice Moisturizing Serum 【Almost New】◉ Used only once in a small amount I received this as a gift from a friend, but I already have one I'm using, so I'm selling this one after using it once. I think it's a very good product! Since it was used only once, there's almost all of it left, but it has been stored at home. Thank you for your understanding! It will be shipped without the box, contents only. Expiration date: 2027.8.21
