The perfect nest for small to medium colony’s, I myself have used these nests for months and months with absolute brilliant success.Two medium sized dry chambers with  the third chamber being lined with super fine mesh to allow for higher humidity.  This nest is suitable for many species such as Camponotus / Myrmica/ Messor and many more!The nest area has some very strong magnets holding the glass lid in place , also included is a red acrylic cover for easy viewing. Size : 90x50x25mm
