This is a flat-type plaster formicarium specifically for ants. The plaster maintains the humidity crucial for ant keeping. How about this for your first ant keeping experience or for expansion? This is a flat-type feeding area that is just the right size, with good height, making it easy to feed your ants. Due to shipping restrictions with Nekoposu and the high cost of sourcing the feeding area, it is priced higher than a flat feeding area without plaster. Plaster Case (Large) will be slightly different from previous cases. The size is the same. Photos 5 onwards show what will be sent. [Features] The case is thin and highly transparent, making observation easy. It is particularly comfortable for keeping a single queen ant or when you have few worker ants. By connecting nests, you can keep colonies from small to large scale.
