Larger than i expected. Made from a semi hard plastic not rigid but tough enough so a child can safely chew on them without destroying them. My nephew has not set his down since he got them last week. He even uses the round tray packaging as their bed. Very happy with these.
Excellent value. Solid plastic shapes. Since these arrived in the post my 3 year old son hasn't put them down. He watches Mister Maker with his shapes. Singing "I am a shape" he even takes them to bed. Great for learning & very educational
