UV Blacklight Pen with Invisible Ink

Secret messages disappear without a trace – until UV light reveals them.

Write a message that no one can read – and then make it visible with a beam of light: the SecretTxt 2-in-1 UV blacklight pen makes exactly that possible. With the invisible ink, the pen leaves no visible traces on the paper. Only the integrated UV light at the pen tip reveals the secret messages. Whether playing with children, writing hidden clues, or as a special gift – secret communication works instantly and without preparation.

Benefits

• No more embarrassing revelations: The invisible ink remains invisible to anyone who doesn’t have the UV light – secret messages stay truly secret.
• No extra device needed: The UV light is built directly into the pen – you don’t need to search for or carry anything extra to decode messages.
• No doubt about quality: The pen is made of eco-friendly plastic and does not require checks for questionable materials.

Usage

1. Write: Use the pen tip with invisible ink to write your secret message on paper.
2. Wait: Allow the ink to dry briefly – the writing remains completely invisible to the naked eye.

Pro tip: The UV light works best in a slightly darkened room – this makes the characters glow especially clearly and distinctly.
