The Joyin 26 Piece Alphabet Robots Learning Fun STEM Toy Set is a unique educational toy that combines learning with play. This toy set features colorful robots that transform letters providing children with a fun and interactive way to learn the alphabet. They also can form 3 larger robots once connected. With the brand JOYIN known for quality and innovation, this toy set is sure to engage young minds and promote a love for learning. I left the cards for each bigger robot in the bag so you have an idea how to combine the little robots. Their pre-owned but all work great and should last a long time.
