Throwing them around and opening them up and looking at the colors. The case makes them super easy to transport and you can take them on your overnight trips as a quick, easy toy to keep your little entertained. A great matching game though with bright colors inside. Different color and number, with corresponding colors and shapes. Learning to count, sort, and match! Extra help with sensory issues, educational delays, gross motor skills, fine motor skills. Kept taking them apart and putting them back together. Enjoy taking them out of the plastic carton and putting them back. They were the perfect size for kids hands. Eggs are easy to take apart but stuck together well. Easy to open but you have to use two hands. There is a tap on the left and right. Eggs are nice and shiny and very colorful. These are just right as far as opening and closing them. Not to tight and not to loose. The eggs are the same size as real ones and the carton (made of plastic) is really nice and cute. The matching colored eggs are easy for a child to put together and take apart. Once kids walked by them in their container on the floor, and pick them up naturally out of curiosity. It's pretty amazing that they can open up these eggs, and there are colors inside. also they can put the eggs back together and put them in the egg container. be assembled with their proper color/number pair. Have fun matching the eggs together and using in pretend play as well.
