Review on 💌 FLYOME Invisible Upgraded Message Goodies: Unleash Hidden Surprises! by Teo Alston

That's it. They say pins, but they're actually markers. My kid thinks he can write on his hand and everything else because it's not visible. So if it was listed as a marker I would look to others for real pens. The markers dry faster, which is my only issue, meaning they can be used in less time. Idk is ok. She likes them, and the price for four was cheaper than the book fair paying that price for one.
