This is an original ant-keeping case made by our store. Hybrid Nest type Slim "Wide" - The glass cover is compact and doesn't take up much space, while also being designed to allow the ants to live comfortably. Type Wide is suitable for small ants, and allows you to observe small ants up close more easily than our previous nests. We have designed it from scratch to allow you to observe and keep ants in a full-fledged yet easy manner. Please note that the cream-colored parts of all products have been changed to white. We sincerely apologize for the change due to the unavailability of the original color. - Humidification is achieved using cotton or sponge, and water can be supplied easily without removing the glass cover of the nest section. - Water can be supplied for humidification using a test tube, making it very easy without removing the cover. Cotton is packed into the test tube, so water will not flow out all at once, and the humidifying cotton in the nest body can be moderately moistened. - Cotton will be packed and shipped with the product. - High-quality glass is used for the cover, making it less prone to scratches and allowing for clearer observation. - There are connection holes on 3 sides, allowing you to freely connect nests and feeding areas, and to enlarge the nest as needed. - It is made with a sturdy construction, so you can keep ants with peace of mind. - The connection holes are screw-type, so they won't come off easily, allowing for safe keeping and movement. - The glass cover is held in place by magnets at 4 points. Suitable for small to medium-sized ants found anywhere in Japan (such as Formica japonica, Messor aciculatus, Pheidole noda, and Crematogaster matsumurai), as well as overseas ants of similar sizes, such as Green Head Ants.
