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

We took this item on a road trip with our grandchildren. They absolutely loved it. Heavy duty, no problems traveling with it for more than 1000 miles in the car. Grandkids ranging from age 5 through 12 all enjoyed it. Highly recommend this item.

It is very nice book! My boy know how to draw a map now!

My son loved this book and pen. He was really intrigued by the light and glow ink. It kept him busy for a while, although some of the activities were a bit hard for him. I didn't mind helping him when he got stuck though, because he was enthusiastic about the book.

It's really cool for a kid but the pen seems to be drying out quick

We gave this to our daughter for her 11th birthday. We were off camping and it was wonderful for the car trip and a fun activity when we had some down time at the campsite. She loved it!

My 11 & 9yo LOVED this book during our 18hour drive! Kept both entertained for a good hour with lots of oohs and ahhs! They loved the little light pen!!

my 9 y/o son loved this!

This is interesting and fun for 7-11years. Notice several reviews talk of there 11 year olds loving it. It is too difficult for a six year old to read.

My son loved getting this for Christmas. He's been writing little secret notes and tucking them away. He's also having a great time seeing what else glows with the blacklight flashlight

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

I bought this for my 6-year old son for a flight. He only watched TV on the plane but this was one of his vacation highlights. He LOVED the activities and was absolutely tickled by the invisible ink pen. He filled in all the pages and doodled and wrote all over the margins. It was adorable to watch him enjoy it so much. I with there were other similar activity book.

My 7 year old has had great fun with this book! Would recommend for journeys, holidays, rainy afternoons!

I love that this is engaging for 7 year boy without a tablet or aggression. He needed help with some of the tasks but that’s the reading level issue rather than product. It seems quite well constructed and the invisible ink pen makes it fun. There’s a spot to store it built into book itself and the pen makes it fun. Only drawback is pen runs out before all the tasks are done but I replaced it in Easter gift.
