How do I set up U-Mask Model 2.2?

It's super simple!

To set up your U-Mask Model 2.2 you simply need to remove the cover and refill from their packages and attach them together. Remember to put the “side wings” of the refill in the holes of the cover and make sure that the “U” is on the right side on your right cheek facing upwards. Also, make sure that the cover covers the area of the refill and it is well positioned on the face.
