Its a beautiful top bar. My bees survived last winter and I split them into 3 hives. Wonderful. The corks in the holes over winter worked OK, but they have now propolized some of the hole so hard to get the cork in. better would be some kind of swing-down or sliding cover.
fast service.. nice top bars.
My bees are happily at work making comb on the cedar top bars that I ordered.
Great quality top bars. Arrived very quickly and in great condition.
