I wish these tiles were around when I was raising my kids! They are incredible. Now all my grandkids have them and I've added to the basic sets over the years.
Not only do the improve manual dexterity, finger strength, coordination (like toys of old did) they are so much fun. Kids use their imagination to build, create, take apart and build something else.
As a Grandmother, I love watching their minds and they create and have fun. I highly recommend Picasso tiles and you'll have enjoy playing with them too.
