Spy UV Pen Toma 0.7/1.0 mm — Invisible Ink Pen with UV Light, Unicorn Design (Mixed)

The Toma Spy UV Pen with 0.7/1.0 mm tips writes in invisible ink that becomes visible only under the pen's built-in ultraviolet light. Housed in a unicorn-themed body available in mixed designs, this pen combines a compact UV torch with a fine and a medium tip option to suit different writing and marking needs. It is intended for discreet marking, verification, note-taking and playful uses where covert ink is required.

Advantages

This invisible ink pen integrates a UV light source so marks remain hidden to the naked eye until illuminated, supporting privacy and subtle verification. The twin tip options (0.7 mm and 1.0 mm) provide flexibility for fine lines or broader strokes. The lightweight plastic body with a secure cap and pocketable size makes it convenient for carrying to events or field work. The unicorn design offers a distinctive appearance that makes the pen easy to identify among personal items.

Suitable for

• Discreet document or property marking for identification
• Event ticket validation and entry control
• Games, puzzles and educational activities involving hidden messages
• Temporary notes and reminders that should remain private
• Quality checks and verification tasks where non-visible marks are needed

Key specifications

How to use

Remove the cap and write or mark the surface using the desired tip size. To check or reveal the writing, switch on the built-in UV light and illuminate the marked area; the invisible ink will fluoresce and become visible under the UV beam. Replace the cap after use to protect the tip and preserve ink integrity. Use on paper, cardboard or other porous surfaces for best visibility; test on a small area if using on non-porous materials.

Usage recommendations

Store the pen away from direct sunlight and heat to extend battery and ink life. Avoid contact of ink with skin and eyes; if contact occurs, rinse with plenty of water. Replace batteries when UV output dims and keep the cap on when not in use to prevent drying.
