I've bought this product many times for my four grandchildren ages 3,4,12 & 13. They never get tired of watching the eggs bubble and fizz while they wonder what will come out. These eggs make wonderful rewards and are fun for all ages to collect.
My grandson loved the dinosaur eggs and now the dragon eggs. I'm sorry you can't get the dinosaurs any more. He gets an egg when he is exceptionally good at school as a reward. They are really fun and a big surprise when they are opened.
