This is an original ant-keeping case made by our store. Hybrid Nest type -C- The glass cover is compact and doesn't take up much space, while also being designed to allow the ants to live comfortably. Please note that the cream-colored parts of all products have been changed to white. We sincerely apologize for this change due to the unavailability of the original color. - Humidification is achieved using cotton or sponge, and water can be supplied easily through the holes at the edge of the nest without removing the cover. Cotton will be packed inside for shipping. - High-quality glass is used for the cover, making it scratch-resistant and allowing for clearer observation. - There are connection holes on all 4 sides, allowing you to freely connect nests and feeding areas, and to enlarge the nest as needed. - The sturdy construction allows for safe and secure ant-keeping. - The connection holes are screw-type, so they won't come off easily, allowing for safe keeping and movement. - The glass cover is held in place by magnets at the 4 corners. Size: 9.5cm x 8.5cm x 2.3cm Glass plate (2mm) Connection hole: For 8mm hose (inner 6mm) Type -C- Suitable for small to large-sized ants found anywhere in Japan (such as Formica japonica), as well as overseas ants such as Green Head Ants, meat ants, and spiny ants.

When shipped, 3 of the 4 holes will have screw-type plugs. Shipping will be via Mercari's Nekopos service. The color will be white.
