Hybrid Nest type F is compact and doesn't take up much space, while also providing a comfortable habitat for ants. It's perfect for initial colonies. We designed it from the ground up to allow for easy and本格的に observation and care of ants. Please note that the cream-colored parts of all products have been changed to white. We apologize for any inconvenience, as the original color is no longer available. - Humidification is easy with cotton or sponge, and watering can be done easily through the holes at the edge of the nest without removing the cover. We will ship with cotton packed inside. - High-quality glass is used for the cover, making it scratch-resistant and allowing for clearer observation. - Connection holes allow you to freely connect nests and feeding areas, and you can expand the nest as needed. - The sturdy construction allows for worry-free ant keeping. - The connection holes are screw-type, so they won't come loose easily, allowing for safe keeping and movement. - The glass cover is held in place by magnets at the two corners. Suitable for initial colonies of small to large Japanese ants found anywhere (such as Formica japonica and Camponotus japonicus), as well as initial colonies of foreign ants such as green-head ants, meat ants, and spiny ants. Easy to observe and care for, making it ideal for children's science projects.
