jbeebase81 Made - Super (Jubako) Beehive Box
Torch-Baked Type

This Super (Jubako) beehive box has been improved annually based on 10 years of experience at the jbeebase81 apiary. The interior is coated with Japanese honeybee beeswax, and the exterior has undergone a torch-baked treatment.

This Super (Jubako) beehive box is the same product as the one included in the Japanese Honeybee Jubako Style Beehive - Waiting Startup Set also listed.
You can observe the growth of the colony through the viewing window, allowing you to visually determine the optimal time for honey harvesting. The lid for the viewing window is easily attached and detached using magnetic fasteners.

Additionally, M6 screws have been newly installed on both sides.
This allows for the attachment of flat bars with bolts to reinforce stacked beehive boxes. It can also be used for lifting with a dedicated lifter.
