Dry erase markers are a great alternative to dusty, noisy chalkboards and make the most of a reusable resource. Unlike most writing utensils, dry erase markers are oil-based, which means the ink doesn’t stick to slippery surfaces like slick plastic, glass, smooth vinyl or dry erase boards. This allows you to draw and print without worrying about making a mistake like permanent markers, and they don’t leave behind airborne irritants like chalk does. But you might be surprised to know that dry erase markers come in a variety of tips, colors and options. Here’s what to look for in a great dry erase marker that meets all of your needs.
