Top Secret: The Ultimate Invisible Ink Activity Book (Klutz Activity Book)

My 8 year old son was entertained with this book and the UV pen for hours. Well written and put together.

I gave this to my 7 year old grandson for a Christmas gift. He loves it. His reading ability is several years beyond his grade level, so I'm not sure it would be suitable for most 2nd graders.

I got this for my nephew’s 7th birthday. He loved it!! He was so excited to find the hidden words on the pages. Great book!

My 6 year old loves this!
