A box of 100 grade 1 Super Frames for BS national beehives. Each box has 11 frames. These are SN4 frames. Grade One HobeeUK quality. Solid top bar from Black Sea pine. Ps: nails not included. ALSO PLEASE NOTE: We regularly recycle clean cardboards for packaging. We take them from a food store and a nearby school. Therefore don’t be surprised if they arrive in a bread box.
