This is our new Terrarium/Reptile Tire swing! This is a super cute addition to any terrarium and is a fun object for your pets to interact with. You will get one tire per order with included string Reptile and plant safe. I would recommend washing it before placing it in your terrarium. We include some string to tie to the top of your terrarium. You may need to modify your enclosure to make it work. Please make sure the tire swing can handle the weight of your pet.
