Bee Thinking Warre boxes are milled in Portland, Oregon using kiln dried Western Red Cedar. Available assembled or unassembled. Our Warre boxes use full 1" thick lumber, 16 screws and rabbet joints for superior strength and longevity. The precision milled, one piece top bars are unattached for compliance with most state and local beekeeping laws. Optional window makes it easy to see in without disturbing your colony -- a great option for new beekeepers!
