Komodo cacti are a great fun addition to any desert style enclosures. They are made from a tough plastic and have no loose or removable parts making them a great addition in bearded dragon enclosures where they may try and chew bits off other artificial plants.
Here's what the manufacturer says about their product:
Artificial desert ground plant for creating a realistic reptile habitat. Weighted polyresin base to keep plants upright. Hygienic, easy to clean & low maintenance.
