About this item
Good quality wooden entrance block with two different sizes. Only issue for me was that it was a few mm too long for my budget National hive (obtained from another supplier) - but it was easy to saw a few mm off one end to make it fit.
Very disappointed with these (I bought two). They came and both are bent, giving the impression they were made of damp wood and have bent since drying out. They arn't much use for stuffing into the entrance of a hive, anyway.
Arrived quickly but unfortunately broken as not packaged very well. A replacement also arrived quickly all in one piece, thank you
Arrived promptly; like the two sizes of opening.
