It's 750g of superior Ligustrum lucidum with a guaranteed content of 100%, and it's a white cloth cover sewn by myself, and it's not filled with buckwheat husk and other things. Just cover it with a pillowcase when you go home. Usually, putting a flat cushion on the pillow directly touches the head and neck, which can play a medicinal role, strengthen the body and be energetic, and is suitable for both men and women.
