How to use: First, take out the wooden letters and the double - sided puzzle boards from the storage case. Then, look at the illustrations on the puzzle boards and place the right letters to spell the corresponding words. It's a great way to learn and have fun at the same time. Note: Keep the small wooden letters away from very young children to avoid choking hazards. When kids are done playing, make sure to put all the pieces back into the storage case. Maintenance: Wipe the wooden puzzle boards and letters with a dry cloth if they get dirty. Don't soak them in water to prevent damage to the wood.
