Join the order of MiNDJACKET! Brand yourself with our Great Seal, and show your dedication to a secret society so secret that no one knows it exists, not even itself.

Most secret societies require a blood initiation, arcane rituals or sacrifice. Those are all fine and good, but I don't have room for both an altar and my press, so just give us $15, we'll give you one of these shirts, and we'll see you at the next meeting.

Features the MINDJACKET ambigram and cool sounding Latin words on it!
