Naughty Santa Packs


After years of testing we have finally released the most amazing way to tell if a child has been Naughty or Nice! Specifically designed for Santas or loving parents, these hand-printed cards literally appear to print themselves right in front of your child’s eyes and in their hands. Visually it looks like an impossible special effect as the word “Naughty” magically appears on the card. See below for more details.

SKU: N/A Categories: ,


How do they work?

The cards are printed with a specially engineered heat-sensitive ink. So when the cards are warm the ink is invisible, as they cool down to room temperature the ink visual fades in.

How do you keep them warm?

That’s easy… keep a hand warmer in your pocket, business card holder, or wallet. You can either purchase an electronic hand warmer or use disposable ones. Disposable hand warmers cost about $0.35 each and last up to 10 hours.

What kind of card stock this?

100-pound matte card stock.

We’ve tested out several different card stocks and colors and have found that this paper is the optimal weight and color to make the appearing cards look truly magical.

What if its really hot outside?

The ink is fully invisible around 92°F (33°C), and will start to transition sooner.  So they are best used at room temperature. If you are a frequent outdoor performer these cards may not be the best choice for you.
