This is a set of four undershirts made of 100% cotton, size 110, in two colors: gray and black. - Colors: Gray, Black - Size: 110 - Material: 100% Cotton Thank you for looking. My only child wore these, rotating through 12 shirts, so I'm selling them because I think they're still usable. Please understand that these are used items. The black ones are in good condition as they weren't worn much. The part of the tag where the name was written has been cut off. #Uniqlo #MUJI #Gunze #Innerwear
