Decorating with phrases and filling our daily lives with optimism and strength is a motivational exercise that has become very popular recently. With the Abbe board letters, you can unleash your imagination and leave messages wherever and to whomever you want. You can use them separately or as replacements for our Abbe board; they can also be a very fun way to introduce young children to the world of reading and writing and thus review the spelling of our language. The letters are made of polypropylene plastic and are available in various sizes.
