Deep size (8-3/8" DEEP) Pierco single wax coated plastic foundation in black color.
You can use them with Apimaye pro frames, Core Beekeeping Core Frames or any other deep size frames you have.
Please note: You can buy the foundation as an option on our hives and supers. That would be cheaper as they would ship in the same box. However this item ships separately so it has shipping priced in.
