Big & Small letters Aa, Bb, Cc, and Dd for teaching trials and level 2-1 of VIPKID. Letters are themed as Dino and his monster friends, blue, green, yellow, pink and pinkball. Three character options for each big letter and small letter, so it's a total of 24 unique letters that you can combine. Choose all Dino, or mix & match with his monster friends. These have been a hit with my shy new students who are learning the alphabet for the first time. **Not a full alphabet, only letters AaBb
