Hybrid Nest 2 side type mk2・small is compact and doesn't take up much space, and it's a nest where ants can live comfortably. The front and back are glass, allowing observation from both sides, and the water supply status is now visible. The cream-colored parts of all products have now been changed to white. We sincerely apologize for the change due to the unavailability of the original color. We created this from scratch, thinking about how to easily observe and raise ants in a本格的に (本格的に - "full-fledged" or "authentic") way. For example: - Humidity is maintained using cotton or sponges on both sides, keeping it clean. (Cotton is included at the time of shipment.) - Watering for humidity is very easy, done through the screw-on hole on the top of the nest without removing the cover. - High-quality glass is used for the lid, allowing for clearer observation. - There are connection holes on the left and right sides, allowing you to freely connect nests and feeding areas, and enlarge the nest as needed. - It is made sturdy, so you can raise ants with peace of mind. - The glass lid is secured with screws at the four corners for stability. Suitable for small to large ants found anywhere in Japan (such as Formica japonica and Camponotus japonicus), as well as overseas ants such as green-head ants, meat ants, and spiny ants. Even ants that cannot climb glass surfaces, such as green-head ants, are fine because of the gentle slope. Easy to observe and easy to raise, making it ideal for children's science projects.
