Perfect conversation pieces that come with a vented hatch on top to keep in those pesky escape artists. A ledge in the outworld allows the upside-down application of fluon and other anti-escape barriers, which are a must for containing Crematogaster, Tapinoma, and other species of ants. These outworlds are 4 inches or 10 cm cubes and are compatible with our own formicaria and antheap formicaria.
