5.0 out of 5 stars Great Travel Activity

J. · September 19, 2024

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.

5.0 out of 5 stars Fun, durable, beautiful product

T.B. · October 26, 2024

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.

Bought this for my 8yo son. He loved it. He liked learning info about spies. He and my daughter used it to make up a spy game and solve mysteries together. I love that it spurred their imaginations.

4.0 out of 5 stars Fun overall

Has really engaged my 7 year old. I don’t like the inclusion of aliens and ufo’s, but looking at the cover that was probably my fault for missing that.

5.0 out of 5 stars Best activity book!

The kids fight over this book. It's fantastic! Highly, highly recommend!

9 year old son LOVED this activity book. Kept him engaged for several hours during road trip. He thought the invisible in was so cool. He also loved sharing some of the jokes and info with his Dad and I throughout the trip.

5.0 out of 5 stars Fun gift for a kid

So fun for a gift

Great

C. · December 26, 2021

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

Good addition for kids party page

P.M. · March 22, 2025

Great for kids party bags. Good price

Works great

C. · December 4, 2024

Works great and exactly what I expected. The invisible ink works great with the black light in the pen.

Great fun, brilliant present for 7 year old

A.C. · December 16, 2021

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

Grandson loved it and spent a good portion of his sister’s birthday using it.

G. · April 4, 2024

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.
