Love to collect rocks and beach glass but have no placd to display? Our rock holders are a really nice display piece and come with fairy lights you can inner twine between them or along the edges. These are made from 1/8" MDF board and have 1/8" acrylic for the front. Easy to fill, just lay down and take the nuts off the back, remove one layer of wood and fill. Replace wood and nuts. Light mounts on the back and fed thru hole in the back. Also has two holes if want to hang instead of sitting on a shelf or mantel.
