Japanese Beetle, Stag Beetle, Kuwalium (Stag Beetle Aquarium) Insect Breeding, Tree Hollow, Natural Wood, Climbing Wood, Perch, and Konugi Chip Set Just the right size With a more natural atmosphere I think you can enjoy the viewing. Please see the images for the size. About Konugi Chips These are sawdust created when drilling holes for raw shiitake mushrooms. Because it's a drill There are many curled (rounded) sawdust pieces. Insects will love it. Since it's not a chainsaw, there's no oil on it. Some bark and moss are also mixed in. I think it can be used as Konugi mat or Konugi chips.
