The Hape Children's Puzzle - Letters includes 27 pieces. Learning the alphabet is now fun. The puzzle pieces can be matched by color, shape, or letter, or you can help your child spell out their name using the colorful alphabet pieces. The letter pieces can be used independently of the puzzle to write simple words and explore words and letters in fun ways. The 26 illustrated pieces inside the puzzle slots correspond to the matching puzzle piece (S for Sun, T for Truck, etc.). The toys are made of wood, using eco-friendly materials, painted in attractive colors with non-toxic paints. They meet the highest international safety and quality standards, such as EN71, ISO9001, ASTM F963, and others. Hape has been creating fantastic, high-quality toys for many years using eco-friendly and sustainable materials, with each product carefully designed to stimulate sensory, physical, and emotional skills.
