Very happy with purchase. It’s made of plastic so it won’t retain odors, hold moisture, warp, deteriorate, and will be easy to clean. It comes with 4 mouse guards/entrance reducers. It fits perfectly under my hive. I’m a new beek so I’m researching as much as I can so I can get items that will help with beekeeping. I also purchased a Vivaldi board which is a 3 in one item. It’s an inner cover, fondant feeder and a ventilation screen.
