What It Says On The Box:
These are a range of purpose built Terrariums for Spiders and other Inverts as used by nearly ever major European Tarantula breeder. Unlike other models aimed at reptile keepers they don't have full mesh top panels causing the substrate to dry out to quickly. The mesh is considerable thicker to stop Tarantulas chewing through and escaping. They have ventilation panels on the front and top which cant be blocked by substrate allowing a cross flow ventilation which prevents stagnant conditions.
The guillotine style front opening doors allows maintenance without having to move the Terrarium off a shelf which is crucial for not disturbing mated or eggsack carrying females. Unlike Acrylic enclosures the do not warp or scratch and glass cools better at night helping with conditioning montane species for breeding
