Thank you for viewing. This is an OMBRA V2 soundproof mask, size M/L. I mistakenly ordered this size when I wanted S/M. I realized my mistake after cutting the tag, so I couldn't return it... (Apparently, the return policy is strict due to the nature of the product.) I've already bought and am using an S/M size, so this is a completely unused item (the one I wanted to return). Since it's unused, I'm not offering any discounts. Thank you for your understanding.
