Thank you for viewing. I purchased these for a hospital stay, but I didn't use them. One set of two was washed and folded. One set is unopened. These are 100% cotton, antibacterial, and odor-resistant undershirts with front buttons, designed to be easy to put on and take off. Quantity: 2 sets of 2 (4 pieces) Size: S - Material: 100% cotton (for undershirts) - Features: Antibacterial and odor-resistant - Design: Front-opening with one-touch tape
