Can a few dollars a box of freeze-dried sleep mask be used?
I can't. The price of the freeze-dried sleep mask on the market is 1 box 19.9 yuan. The freeze-dried sleep mask with several dollars per box is far below the market price, so it is not a qualified product and cannot be used. Mask is a kind of skin care products, which is used to replenish moisture to the skin, and also has many functions such as moisturizing, moistening, nourishing, improving appearance, deep cleaning and so on.
