This is our original small insect (ants, pill bugs, etc.) breeding case. Hybrid Nest DIY・wide is a nest based on the conventional Hybrid Nest that can be decorated to your liking. You can lay sand or soil, arrange stones and moss, or use it as is, allowing you to customize it for your needs. Cleaning the watering area is easy, just slide the glass cover, so you can do it calmly without worrying about the ants escaping. All cream-colored parts of the products have been changed to white. We are very sorry for the change due to the unavailability of the original color. Please choose the connection hole size from two sizes. - For moisture retention, use cotton or a sponge, and replacing the cotton is easy by simply sliding the glass cover. - Watering can be done through a small hole on the side, allowing you to water without disturbing the ants. - We will ship with cotton packed inside. - The cover uses high-quality glass, making it less prone to scratches and allowing for clearer observation. - There are 4 connection holes, so you can freely connect nests and feeding areas, and enlarge the nest as needed. - It is made sturdy, so you can breed with peace of mind. - The connection holes are screw-type, so they won't come off easily, allowing for safe breeding and movement. Screw-type plugs will be attached to all four holes during shipping. - The glass cover is held in place by magnets in three places, and there is also a catch on the other side, so the cover will not come off easily. Suitable for small to large-sized ants found anywhere in Japan (such as Formica japonica), as well as foreign ants such as green head ants, meat ants, and spiny ants, and other small insects such as pill bugs. Easy to observe and breed, making it ideal for children's science projects. Shipping will be via Rakuraku Mercari Bin Nekopos.
