This 5-frame nuc observation hive is perfect for educating both adults and children alike. Pull a frame from the nuc and place in the observation hive. Be sure to find the queen and place her in the upper section. The removed frame can be replaced with a division board feeder full of sugar syrup to feed the bees while caged. When not using the observation window move the frame back down below and let the bees fly freely until needed again.

Fits 9 1/8" frames. FRAMES NOT INCLUDED
