Illuminate your mason jars with this LED lid insert. Easy to use and perfect for creating a cozy atmosphere. Ideal for DIY projects. I have had this for a very long time, but it has never been removed from the packaging. The back has instructions and shows that it takes batteries, no batteries included. There are also 4 different non lighted lids with different functions. Along with 2 sealed packs, 4 each pack, decorative mason jar lids by the pioneer woman. All are new. Please feel free to ask questions.
