The "used condition" means this Acme T-Shirt has been previously worn. We've inspected it carefully to ensure it's in good shape, with no major damage like holes or excessive wear. It has been washed and is ready to wear. The 'Lithograph - 9" x 12"" design is still intact, and the cotton material, though pre-shrunk, may have a slightly softer feel from previous washes. Overall, it's a quality, comfortable tee looking for a new home!
