Non medical grade cotton mask is an adult SM/MED(10”x5.75”) which is the size that fits most, even men. It is double layered, re-useable and washable (hand wash preferred). Both elastics have silicon buckles that are fully adjustable to fit all face shapes. DISCLAIMER: Due to high demand and shortage of elastics, ear loop elastics will come in WHITE or BLACK. I cannot promise a certain color for you. Mask inner lining fabric may also differ from photo. No returns‼️Thank you for understanding.
