Are You Careful On Signal? Postcard

Are You Careful On Signal? Postcard

$3.99

Because your M-4 doesn’t leak classified info — but your thumbs might.

Inspired by WWII-era propaganda and 2025’s most infamous OPSEC moments, this Are You Careful On Signal? postcard is the perfect pocket-sized reminder that tactical silence is sometimes the loudest message. Whether you’re sending it to a battle buddy, a Signal thread regular, or just framing it above your desk, this card speaks volumes—without the emoji.

Printed on durable, high-quality matte paper with a coated surface, it’s built to withstand both international mail and internal investigations.

Specs:

• 4″ × 6″ of vintage-style vigilance

• 0.34 mm thick cardboard paper—tougher than most passwords

• High opacity and a clean matte finish that says, “I don’t overshare.”

• Blank back for your message, coordinates, or stern warning

Perfect for:

• Lighthearted jabs at your OPSEC-challenged friends

• Motivational morale mail

• Replacing that worn-out “Think Before You Share” sign in the office

Because when it comes to secure comms, the only thing that should be firing off is your weapon — not your Signal chat.
