Hachi Mitter For Japanese honeybees - Queen Bee Escape Prevention Device This device is equipped with wire mesh of a width that allows worker bees to pass through but prevents the queen bee from passing. Size: Bottom plate: Approximately 28.8cm x Approximately 7.8cm x Approximately 0.8cm Top: Approximately 20.4cm x Approximately 7.1cm x Approximately 4.8cm Purchased several years ago and used for only 2 years, then stored. There are scratches and stains. Please consider if you are not concerned about these. Photos: Photos 1-3 show the device in use after purchase. Photos 4 and later show the actual items for sale. When used with a homemade beehive, wood has been attached to fill gaps. It is attached with tape, so it can be removed, but leaving it as is to avoid damaging the wood if removed forcibly. Some have already been removed. I will choose which ones to send. 1 piece: 2150 yen 2 pieces: 3550 yen 3 pieces: 4700 yen 4 pieces: 5900 yen *Please be sure to read the profile section. *Please refrain from price negotiations. *If you have any questions, please inquire before purchasing.
