Medium hex, tennis balls not included, nor spongebob!
1- Medium 4.5" mesh lid vented hex container
This large hex size: 6 1/2" x 9 1/2 x 8.75". This hex is fab, as you can see it has 5 sides you can turn it onto, 6 including the lid. I like this feature for mantis that are molting, if the mantis is apparently in the wrong position you can turn this hex to help it without disturbing the mantis. This size hex is good for medium to large mantis and spider caging or any other insect that needs a large home. Mesh Vented with feeder hole included.
