Frequently Asked Questions
Q: How does the invisible ink pen work with the UV LED keychain light?
A: The invisible ink pen uses a UV-reactive ink formula that dries completely clear and undetectable under normal lighting. When you shine the included UV LED keychain flashlight over your writing, the ink glows and becomes visible instantly — making it perfect for secret messages, scavenger hunts, and party games.
Q: Is this invisible ink pen set safe for children to use?
A: Yes! The set is designed to be suitable for children as well as adults, students, and teachers. The pens are made from durable PP material and contain no high-concern chemicals, making them a great choice for school projects, creative crafts, and family activities. As always, adult supervision is recommended for younger children.
Q: Can the invisible ink be used on any type of paper or surface?
A: The invisible ink works best on standard paper, making it ideal for notes, documents, cards, and school assignments. Results may vary on heavily textured or dark-colored surfaces. For best results, use on white or light-colored paper and allow the ink to dry fully before revealing with the UV LED light.
