The URS Beastie Box is ideal for temporarily keeping juvenile reptiles of many species. They can be used by placing holding containers, stacked centrally, in a reptile enclosure or in a rack system with half of the container on a heat mat or heat cord. URS Beastie Boxes are not reptile viviariums; we do not recommend them for long-term use for larger reptiles. Size = Length 29.5cm x Width 19cm x Height 14cm.
