Eight Push In Queen Cell Protectors.
Great for housing capped swarm cells cut from brood comb without having to pare down the attached comb so reducing the chances of damaging the unemerged queen. Just push the two spikes into the wax comb and drop the Queen cell in. Looks like a little basketball hoop.
