These silk plants are great for mantis enclosures, especially mesh cages of all sizes, and are 100% safe for your pets! You pet mantis will love the cover the plant creates, and will very much appreciate having something else to hang from in their home besides the top of the enclosure itself.
The stem can be bent or cut to the desired size for your enclosure. And they hold their shape when bent, so they can even be wrapped around a stick or other object in the enclosure.
The full stem is about 20 inches long, and several inches of that is just stem which can be easily trimmed off with tin snips or wire cutters without damaging the leaves themselves.
