Glass Terrarium Nano Reptile Breeding Cage GEX Size: W21.5 x D21.5 x H33cm I kept one tree frog in it for about 2 years. I did not use soil in it. The styrofoam background has small holes where mealworms ate it (photo 4). Also, the four corners are slightly damaged as they were removed during cleaning. Although I cleaned it thoroughly, please understand that there may be some water stains that could not be completely removed. There is no outer box, so I plan to wrap it in bubble wrap and ship it in a cardboard box. Please consider this if you understand that it is a used item.
