It's a simple modeling pack.

This is a modeling pack I always pick up when I go shopping at Daiso. It is the Lindsay Modeling Pack. Open the pack, add about 7 tablespoons using a large spoon, and mix quickly. I recommend starting with 6 tablespoons and adjusting the amount. Then, using the enclosed spatula, apply a thick layer starting from the cheeks to the forehead, nose, and chin.

After using it, just peel it off and your skin becomes incredibly moisturized and radiant. I switched from sheet masks to modeling masks and saw immediate results, so I use this regularly.
