The pens work well fun for sending secret messages a lot of ink and easy to use just write and use light to reveal the message. A+

Our daughter had invisible ink pen on her Christmas list so we found these. They work great! Our cat even had her belly shaved when she was spayed recently and our daughter drew a heart on her belly and one day she says, " mom look " and shines the special light on our cats belly and I just see a glowing heart, so cute. It stayed there for about over a week. These are really cool and fun pens. A great gift for sure. Definitely recommend.

These work good, pretty invisible till you shine the special light on it. Only complaint is the the 'ink' or whatever it is , is all the same color! What's the point of 7 colored pens when they all write the same? Maybe I'm too old to understand it; kids like colorful things to write with perhaps.

I was really looking forward to leaving invisible ink messages in a book as a gift but the ink faded away in an hour. It’s great for if kids want to use the but not so much for adults.

This pack was a good price, comparatively. Each of my markers worked; all inked the same color under the UV light except the green and pink pens, which had ink with a slightly bright yellow-green color. The batteries for the light on each pen are not activated until you pull out a paper seal, so you can keep them in storage until use without the batteries running down. I'm using one and giving one other to my fiancee so we can write little notes back & forth. I like to put notes in his lunch or in pockets, or just randomly around the house. This will be fun!
