These shirts usually start as misprints or extra stock. Instead of throwing them out, we use them for practice, sampling, or to test a screen before printing. They end up covered in all sorts of designs and look like no other shirt you'll own! Can be exchanged for another size, but can't be swapped for a different tester print. A Portion of All RAYGUN Sales Raise Money For . A Variety of Screen Prints on a T-shirt (test prints are primarily a mix of 100% cotton shirts and 50/50 blends). Cut and sewn . Designed and printed by  at RAYGUN.
