Size = Length 300mm x Width 210mm x Height 95mm Click Clack Holding Containers are ideal for temporarily keeping juvenile reptiles of most species. They can be used either 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. Click Clack Holding Containers are not reptile viviariums; we do not recommend them for long-term use. These containers are dispatched as airtight and small air holes must be drilled prior to any animal being placed in them. Made from sturdy plastic with metal clips and a clear lid, very easy to clean.
