Thank you for viewing. How about this for raising crickets, roaches, dubia, etc.? It's handmade, so the shape is distorted, but it should be fine for raising insects. It's made of plastic, so you can wash it thoroughly if it gets dirty. It can be used repeatedly, so it's hygienic. The approximate size is as follows: Length 15.5cm, Width 12.0cm, Height 3.0cm
