Yes glass works well as a dry erase board! A vinyl marker board is a no-go.
We call them thINK boards. Tempered low iron glass is crystal clear. Using this type of glass insures that your back painted color of choice is viewed correctly with no artificial tints or hues. If you'd like to add corporate branding or custom artwork, we can digitally print your high res images on the second surface of the glass before back painting begins. All done in-house at our shop in, Houston, Texas.
