Invisible Ink Spy Pen With Built In UV Light Magic Marker 1pcs

Fun and curious. Arrived after 5 weeks. It's practice. Write even when you can't see yourself, as they say. But the ink that you can't see doesn't come off with water, only with more abrasive products.

The marker can be smudged off in an instance. Also, it’s barely visable when you turn the flashlight on, and the marker itself came kind of dry so it was quite hard to apply.

It's super great for my daughter, but unfortunately it was already her birthday and it was too late. Otherwise great. I can recommend. 👍

Exactly as indicated, it works very well for the little sweet words to my husband.
