I'm selling these as I purchased them about two years ago and used them for a few months, but haven't worn them much since. They will be shipped in a Muji clear case. There may be a unique smell from the case, but it should disappear once you take them out. Please be aware of this. - Updated lenses with anti-fog coating. - Approximately 45% plant-based materials used in the plastic parts. - Reduces blue light by approximately 25%. - UV400 lenses that cut 99% of ultraviolet rays. - A casual design that combines plastic and metal frames, not overly classic. - Versatile enough to be used in various situations.
