Product details at a glance

What’s inside the set?

You get 12 invisible ink pens, each with a small UV light at the top, and 12 mini notebooks. Every pen and notebook is decorated with custom space artwork—planets, rockets, stars, and astronauts—turning them into collectible keepsakes rather than throwaway party items.

How do the invisible ink pens work?

Kids write a message on the notebook paper using the pen. The ink is invisible to the naked eye. To read the secret message, they switch on the pen’s built-in UV light and shine it over the writing—the text glows and becomes readable. No batteries are needed for the UV light; it’s integrated into the pen cap.

Who is this party favor pack for?

It’s designed for children aged 4 to 12, making it a versatile choice for birthday parties, school events, classroom prizes, or any space-themed celebration. The spy-kit appeal also works well for sleepovers or holiday gift exchanges.
