Anything you write or draw will look great on these boards, especially with colored chalk or liquid-chalk markers. Little chalkboard signs can be a great way to leave decorative notes and messages for each other. Erasable and Reusable Our Erasable chalk boards are made of sturdy 0.1 inch thick acrylic material, and they can be easily erased with a dry cloth or damp sponge, so you can use them again and again. For couples and families whose schedules don't overlap as much as they might want, some little chalkboard signs can be a great way to leave decorative notes and messages for each other. In stores and shops, chalkboard signs are a highly effective way to communicate with customers. Whether it's an informative sign, a pointer to a tip jar, a joke-of-the-day, or just a friendly greeting at the front door, customers know that chalkboard signs were created by a real person and not a machine. This makes customers feel more connected to the people behind the business, which is always a good thing.
