Working interactive Smart Board. I'm like new condition. Great for an office space, school environment, even at home for home schooling, Etc. comes with speakers on both sides, tray to plug in the markers, and smart projector. You are able to use the markers to "draw" on videos and things that are being projected. Got them from a college that closed down - they only used them for approx. a year. Long enough to know how useful they are! More information upon request.
