Excellent activity cards for 4 years and upwards I would say. There are loads of double sided dry-wipe cards, great for anywhere, in the car, at home, waiting for appointments, etc, anywhere the children need to be occupied. As a teacher I bought a few sets for my class and they love them, the cards are robust, well designed and have really stimulating colours and activities. Highly recommend. Excellent value for money. I bought 5 of these with different themes and unlike others comments all the dry-wipe pens worked well. Will definitely be buying more for presents!
