Material is too strong,big and NO DELICACY !
The quality of the paper is so tough that it touches the face, so it rubs the skin when speaking and is harsh on delicate women's skin.  , The mask is curved by applying pressure with a machine, so that part is sharp like a knife.  Very uncomfortable.  It's bigger than I expected, so it sticks out of the mask. About 3 hours after starting to use, the fibers of the paper peel off and enter the nose.  This is the most unpleasant。
