With summer around the corner and no school (what’s that? We haven’t attended school in ages, and I’m not the only one around here who misses it!) for the next couple of months, we want to keep our kids in the habit of writing. There’s no better way to do that than working up some enthusiasm by grabbing several of these novelty Invisible Ink Pens.

These pens come with a blacklight built into the cap of the pen. Use the invisible ink to write a message, then shine the light to reveal the writing. A simple button turns the light on while pressed, and the three tiny batteries can be replaced (if you have the right kind on hand). All the pens write in the same ink color, though the pens themselves come in a variety of shades.

Turning on the blacklight in the cap of the pen reveals the hidden writing.

My five year old who hates even writing his name got one of these pens in a birthday goodie bag. He adores it. He loves writing secret messages to his friends that only they can see. He also loves writing things hidden from his siblings. These affordable pens work great as prizes, favors, and for pen pals of any age.
