Contraptions Tee

Forget sleek. Forget standard. This shirt is for the builders, the breakers, and the brilliant improvisers. Featuring a blueprint-style graphic of a homebrew 6-pellet contraption launcher—complete with electrical cords, vinyl tape, and unapologetic ingenuity—this design carries the bold message: “Never send a gun to do a contraption’s job.”

Perfect for tinkerers, makers, rebels, and defenders of the unconventional, this limited edition Rock City Defense tee fuses DIY spirit with militant creativity. Printed on ultra-soft, durable cotton, it’s made to survive the shop, the street, or the next recon mission.
