2- Small rectangle. Excelsior and ball not included.
2- small rectangle cloth lid/ feeder hole
Small rectangle size is 4" x 4" x 5 3/4" high. This medium rectangle is good for hatching oothecas and housing for small adult mantis. I like this feature for mantis that are molting as you can turn it on any side. Vented with lid and a feeder hole included. Comes with cloth lid, mesh or plastic available
