This is a set of 5 men's underwear: 4 T-backs and 1 brief. The size is XXL, as indicated at the time of purchase. The blue and light gray ones have glitter. The silver metal on the upper left has some adhesion issues and is peeling. This set is recommended for those who don't need 10 pieces but want a few. Please consider purchasing. Note: This is an overseas product, so no returns or exchanges are accepted. P.S. I'm running low on men's items.
