Congratulations! You have not only chosen style, but you have also chosen safety. What fabulous taste. This mask is made of the highest quality fabric, a combination of 100% Silk for the front, and 100% Cotton percale for the back. The combination of the two natural fibers allows for breathability & comfort whilst still ensuring no liquids exiting your mask due to the close weave. Tie a knot in your elastics or hand stitch to ensure the best fit for your face if needed.
