As a detective, you need the right equipment for your investigations, including tools for writing and uncovering secret messages. Exchange confidential messages with your fellow agent using disappearing and reappearing ink that only the two of you can read! Using either of the two secret pens, you can write a message that, once dry, becomes invisible. The other pen will not only reveal the information, but you can also use it to send your reply.

Review: simple but fun - This review is for the Thames & Kosmos Spy Labs Inc: Secret Message Tools Exchange Confidential Info w/Secret Pens. The metal storage tin is cute and useful. The kit consists of a small notepad, a petri dish, 2 pens, 1 brush, and a small info insert. The first secret message method is using the magic pens. The second method is to use household items like milk or juice from lemon, apple, or onion and then to reveal the dried message using heat from a 400 degree oven. This kit is small but fun. My kids have used invisible ink UV spy pens in the past and had fun. I think that they’ll like adding a few new methods for writing secret messages.

### ⭐⭐⭐⭐⭐ Fun, simple activity
*by T***R on December 29, 2024*

This item is easy to use; just write on it with one of the included pens, then draw the other pen over it to reveal what was written. There’s no bleeding onto other pages, though that might change if you try the experiments listed in the booklet using the paintbrush to paint different materials (haven’t tried that yet, but it seems fun!). It’s kinda strange that each page is pre-printed with a message that takes up most of the page; would be better to have the pages blank in my opinion. Price is right for what you get, and I like that this comes in a tin you can store everything in.
