Funny Acronym Mug — "Probably Invalid Number" (PIN) Coffee Mug

"Probably Invalid Number" — say it without saying a word. A funny coffee mug and gift for the tech person in your life.

Who it's for: the coworker locked out of email, the dad who forgets codes, the IT help desk tech, or yourself — buying it for yourself absolutely counts.

When to give it: Secret Santa, Father's Day, white elephant — or any password reset day.

Why it works: It lives on the desk, not in a drawer: every coffee refill is a small reminder of who gets their sense of humor.

• Printed in full color, the same design you see in the photos
• Dishwasher and microwave safe — the joke keeps its shine
• About 4.6" tall, 3.4" across the base
