Printed on a female-cut Bella 8809 tank in “Black” with white plastisol ink.
For more information on the blank (which includes a size chart), click here and view the “Black” blank on the color chart. That page has some additional model pictures so you can get an idea of how the tank fits. It’s official described as a flowy high neck tank.
This is the same tank as our Black / Gray female tank for sale here and our Gray / Pink female tank here.
