This is a set of 7 T-shirts, one for each day of the week, printed on them. I used to wear these every day to the gym. There are stains and yellowing. The Wednesday shirt is a different color because I went to the gym most on Wednesdays. I stored these at home for many years after I stopped going to the gym. They may be sent compressed. Please purchase only if you understand this. Size: M (probably men's) I usually wear a women's L, but these have a loose fit.
