Old-school chalkboards. What a pain! They screeched, it was a pain writing with 1/2" pieces of chalk, and banging erasers against the board to clean them resulted in a head full of chalk dust. With Dry-Erase Whiteboards and good-quality accessories, you can create bold, colorful, and easy-to-read presentations. When you're done, writing disappears quickly and easily, without a mess, or the need for a ShopVac.
