This is an Unused NBA New York Knicks Glow Necklace. The necklace, when connected glows and flashes a blue light. We are selling each necklace as is, as some at the time of this listing do flash and other don't. Some of these necklaces may need new batteries. We can't guarantee that every necklace will work and some may have weaker batteries. The necklace is a must have for the collector. Makes a great gift or treat yourself.
