The listing, Light up display fixture has ended.
This is used for placing any object with a bottom surface that would allow light to shine through. For example cut crystal. This display lights up and makes your collectables beautiful. The light waves in and out to a slow rhythm. This one does have a outlet for a plug but I never had it, I have used batteries and they have lasted forever because I would usually only turn on during special occasions or holidays. This one produces white light. I have another smaller one listed that creates colored light. They both work but I am keeping my batteries I have a few other things that needed them.
