If you mean how are they shipped, they are in a shipping box. It has screens around a couple sides, the queen is in a cage, and a syrup can is hanging in also. When I transfer them to a hive, I use a divider to reduce the size of the hive, put a frame with some open brood for them to tend, and pour them in. Then suspend the queen cage between the frame of brood and another frame, and pull the plug. It takes a couple days for them to eat the candy and release the queen. The open brood is key and keeps them from absconding in most cases. I also put an extra super on and give them syrup as fast as they will take from above the inner cover. I try to do it in the evening. so they have no choice but to settle in.
