What a lovely idea for simple compact fun on the go. I had a long haul flight with my 4 and 6 year olds and these were perfect to pull out the bag at key moments of need! they found it fun exploring the different cards in each box. there is no mess and it is all easy to put away. I think these are handy to have in the car/for travel and have reusable activities. a thumbs-up from me!
