This eye mask was created after studying the effects of just the right amount of pressure, such as the sense of security when hugging someone or the comfort of being wrapped in a futon. Its pea pod shape keeps the beads inside even and maintains just the right weight at all times. When placed over your eyes, it covers your ears, blocking out light and sound. Each side is made of a different material, allowing you to enjoy two sides: incredibly smooth fleece and soft jersey cotton.
