Your cart is empty.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. From Spy Labs, the Detective Gear Experts!

I think it's a bit too simplistic, even for just trying to start someone new on the concept.You get a limited amount of invisible ink, but it tells you "oh you can make more with lemon juice".So you're just paying for a pad of paper and a pen that will run out quickly?

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.

This kept my 8 year old occupied for about 10 minutes. I'm sure he'll come back to it at some point, but the kit is small and not that great.It contains two pens, a small dish and a little brush:The dish and the brush are for an experiment to smear lemon juice or milk on a piece of paper, allow it to disappear and then develop it by heating the paper to 200 degrees for 5 minutes (with supervision!)One of the pens writes in invisible ink. The other pen enables it to be developed.That's it!There are other sets out there with little UV lights or bigger, better pens. The only thing this has going for it is that it's cheap and compact. Like all toys from this maker, the instructions are engaging and pretty good, hence 3 stars and not just 1.
