Here is your answer! These wall mounted displays hold 6, 12, or 18 nightlights lit properly so your customers can easily appreciate the intricate designs of the Lithophanes. They are sturdily constructed of solid wood, with a cherry wood finish laminate background for contrast. We use industrial grade electrical outlets for durability; these displays will last for years! Best of all, they don't take up much wall space, so you can make a good presentation in a relatively small area. Complete with a six-foot cord and an in-line switch.
