Review on Erasable Chalk Markers For Glass, Whiteboards & Chalkboard Paint - Refillable Ink In 5 Colors! by Marcus Price

These markers are great for people who want to avoid the dust and mess of traditional chalk but still want that classic chalkboard look. The ink flows smoothly and cleanly, and it's great that they're refillable so you can use them for a long time. The variety of colors is also fantastic, and they work on multiple surfaces. However, the ink does tend to start fading after a few hours, so if you need something that will last all day, these might not be the best choice. Overall, a decent product that gets the job done.
