A pillowcase is an outer cover that protects the pillow. It is usually made of soft cotton, silk, bamboo fiber, etc. It not only protects the pillow from stains, dust and allergens, but also improves the touch during sleep and increases the comfort of the pillow. Pillowcases are rich in design, with various styles and colors, and can be easily removed and washed to keep the pillow clean and hygienic.
