Thames & Kosmos Spy Labs Secret Message Tools, Detective Toy with Invisible Ink Pen for Exchanging Confidential Messages, Toys to Develop Problem-Solving Skills, Age 8+

This is incredibly overpriced for what it is. It’s basically 2 pens and a tiny bit of paper. It claims it’s for ages 8 and up but requires heat to use. Incredibly disappointed and a waste of money.

Bought this as a gift .they seemed to enjoy it!

I bought for my knees who likes to be detective . You need another player to play this .

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.
