3 Pcs Invisible Ink Pen with 3 Pcs UV LED Keychain Flashlight, Spy Pen, Disappearing Ink Magic Pen for Secret Notes, Magic Spy Marker with Purple Light for Christmas Halloween Holiday Present

Super cute and fun stocking stuffer for the kids for Christmas. They esp love using the little light for many things besides just seeing their writing. Pens work well and dry quickly and they liked the bright colors.

So cool to send secret messages with my grand-daughter! We have so much fun with this & our black paper

All pens work, great for craft projects. Works exactly as expected.

When I got the product everything was going well until I opened the pink one and it did not work!! I was kinda disappointed because it took a veryyy long time to get it. The blue and yellow colors look the exact same but it's not a big deal. But for 9 dollars is really good! It's not to expensive but not to cheap, the quality for a pen for 9 dollars is pretty dang good. The flashlight's durability is really fragile and cheap. The pens are really high quality!! I don't really understand how or why the pink didn't work and I'm still sad about it but I would probably buy this again! :D

These worked well to number my ivory wedding RSVPs. And I actually got to use them once as someone did send back an RSVP without a name! I tested these on several types of paper and discovered that they don’t work as well on darker papers, the markings are faint, but still visible if you are looking or paying attention. But on light paper, you couldn’t tell at all!

These are great! We used them to label the back of each wedding RSVP with a number so we could figure out who it was from - in case of hard to read lettering and/or they don’t say who it is. Once the ink dries I couldn’t even see it! And with the light provided it was easy to see! Highly recommend if you want an invisible ink pen that’s at a great price!!

These are very fun. They work as stated. I think the pink one comes out the best because it's more vibrant than the other colors. The quality is on the lower end, but that's to be expected for the price. Also I think it does better on white than on black.

At first the blue pen wouldn't work under the black light so I shook it and tried again and it worked after that. I used this product to make a Tomb Raider themed card with "secret runes" to solve. Worked out really nicely. I used specialty parchment and the ink didn't bleed out too much and provided sufficient color without being too much. They dried quickly and worked quickly.
