I have to say, hands down, these are one my favorite accessories for the holiday season. We purchased a few of these for a recent holiday decor project. They’re Pottery Barn’s Lit Mercury Glass Globes. They’ll add such a soft warm glow to any decor. They are hollow and have a hole on the bottom for inserting a string of battery operated lights. If your room is in need of something/anything?? this could be it. And to sweeten the pot they’re on sale right now!!!
