There are different letters on either side of the unicorn pieces; For example, Aa on the front and Nn on the back. When lined up in order, Aa--Mm are on one side of the unicorns, and when flipped over, there is Nn--Zz on the other side. Toddlers and preschoolers who are in the early phase of learning the alphabet can match the letters they do know while learning something new on the opposite side at the same time. The high-quality educational toy can teach several things, such as colors, sorting, letters, and help with fine-motor skills.
