• Separates ABG mix and other substrates from the drainage layer to support proper airflow, water flow, and humidity balance in bioactive terrariums
• Made from flexible, lightweight material that is durable and gentle for reptiles, amphibians, and invertebrates such as geckos, frogs, tarantulas, snakes, salamanders, and skinks
• Mesh is fine enough to block loose soil and debris while still breathable, allowing effective drainage and preventing stagnant water in the tank
• Includes three 18.1" x 18.1" reptile substrate barriers that are easy to cut to size, with extra overlap to wrap edges and stabilize layers in standard 18" x 18" tanks or custom enclosures
