This is an original ant-keeping case made by our store. The Hybrid Nest 2 side type I glass cover is compact and doesn't take up much space, while also providing a comfortable habitat for ants. The front and back are glass, allowing observation from both sides. We created this from scratch, thinking about how to easily and properly observe and keep ants. - Humidity is maintained using cotton or sponges on both sides, keeping it clean. (Cotton is included upon shipment) - There is a hole at the top of the nest, allowing you to manage the nest's humidity by providing water to cotton, etc. - Watering for humidity control is very easy, as it can be done through the hole at 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 to enlarge the nest as needed. - It is built sturdy, allowing for worry-free ant keeping. - The glass lid is secured with screws at the four corners for stability. Suitable for small to large-sized ants found anywhere in Japan (including *Camponotus japonicus* and *Camponotus obscuripes*), as well as foreign ants such as green-head ants, meat ants, and spiny ants. Even ants that cannot climb glass surfaces, such as green-head ants, will be fine due to the gentle slope. Easy to observe and keep, making it ideal for children's science projects.
