Basic Dark T-Shirt, Navy Blue, Small
I found the shirt quality itself to be well made. Unfortunately I found that the image quality of the artwork is low resoultion. So the art and words aren't as clear. I probably wont buy another shirt to be honest, but I'm glad I supported the podcast of which I'm a fan of. I was just hoping that for the price I paid, it would have been of better quality.

this was good quality and perfect colour. Printing was great although when we all opened our secret santa gifts one of the other mechanics commented whoever got that for him missed out part time after the word mechanic Sorry I don't have any photos
