Ideal for schools and fairs. Over the years, we've sold hundreds of these Observation Hives to teachers and farm stand operators. They're ideal for anyone who needs to give a demonstration on "bee-life." This two-deep frame hive features plexiglass windows for enhanced safety and a built-in feeder (which can be refilled without any bees escaping.) Built-in sliding covers (on BOTH sides) provide a dark nest for your bees when you are not observing them and gives added protection while in transport. Ventilation ports on each end help keep hive moisture at proper levels. Features a wide, solid oak base for maximum stability. Available assembled only. Dimensions: 28-1/4" x 6-3/4" x 23-1/4". (Ship Wt. 30 lbs., ships in its own oversized box).
