This was a gift for my 10 year old daughter. She loves it and it works well. My only complaint was it took us a bit to figure out how to put it together. I though the directions would have been a little clearer.

While this is a fun concept and definitely made me relive some of my childhood memories. The pen requires assembly because the ink cartridge needs to be installed and to do so screws need to be removed but the hardware and tools were not included. Even though it comes in a large tin can, and there’s a lot of space to provide tools in it this does not come with any tools. It also requires a AAA battery which was not included with my pen. While it is neat to call this a spy pen the other person really needs to have this pen as well because you can only see the writing under the special light that is included on the pen.

What a fun gift for my kids, they definitely had fun with it. It does need some assembly, and it isn't anything super fancy, pretty much just a cheap marker and light, but it works as it should and perfect for a kids toy.

This toy is so nostalgic for me. I love that it's a whole kit in aTin box. It's so easy to use. I originally got it for cyphers in D&D but this proven to be equally as fun to write secret messages to my son. He absolutely loves this toy now too. It comes with everything you need from write the messages and also to be able to see them after you've written it. This would be a great gift for kids and adults alike. I think many adults would feel nostalgic for this. It well made and has gotten tons of uses in my house eso far with no signs of wear and tear.

This was easy to put together. The light is a bit small, but it works fine. We used a bigger UV flashlight that I already had, to be able to read more at a time.The kids did a scavenger hunt where they had to use the light to read their clues that were written with the invisible ink.Such a fun little gift!

I feel like they spent a lot more money on the tin and packaging than the actual pen. It was a little frustrating to open the package and then have to go find a tiny screwdriver to assemble the pen. It does work as expected and it is fun to write invisible notes but it could be better.
