This is the Round Lab Birch Sap Moisture Mask Pack I bought during the Olive Young sale.

First of all, the exterior is pretty with its white and blue combination.

It maintains moisture balance using birch sap.

Hyaluronic acid supplies moisture to dry skin during the winter, revitalizing it to keep it hydrated and refreshed.

It is a 100% pure cotton sheet, so it adheres softly to the face.

I think it is a powerful mask pack for hydration, and I really like that it is a Korean product.
