This is the "Wool Blend Regular Collar Shirt" from MUJI Labo, released last year. The color is black, and the size is L. I purchased it last year from MUJI's online store. The difference from this season's model is that it has a chest pocket. It is new and unused. It has not been taken out of the bag, and the tags are still attached. There is no smoking or pets (dogs or cats) in the house. No stains, tears, or odors.
