Hybrid Nest 2 side type H・MK4 ・small This model allows for easy removal of the existing 2-side type's water-absorbing cotton, making it simple to check the cotton's moisture level and refill the water. All cream-colored parts of the products have been changed to white. We sincerely apologize for the change due to the unavailability of the original color. This product was created from scratch with the aim of allowing you to easily observe and keep ants in a本格的に manner. - Moisture is maintained using cotton and sponges on both sides, ensuring cleanliness. (Cotton is included upon shipment.) - Depending on the environment and preference, you can also use plaster instead of cotton. If the plaster becomes dirty, soak it in water to soften it, scrape it out, and then pour in new plaster for repeated use. - Magnets make it easy to remove and attach the water supply section. - High-quality glass is used for the lid, allowing for clearer observation. - Connection holes on the left and right sides allow you to freely connect nests and feeding areas, and enlarge the nest as needed. - The sturdy construction allows 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 (such as Formica japonica and Camponotus japonicus), as well as foreign ants like green-head ants, meat ants, and spiny ants. Even ants like green-head ants that cannot climb glass surfaces are safe due to the gentle slope. Easy to observe and keep, making it ideal for children's science projects.
