Reptile layout supplies This is the backboard for the GEX Exoterra Glass Terrarium Nano PT2601. I purchased the Glass Terrarium for keeping frogs, but I solidified the walls with modeling clay, so I never used the backboard. It seems unlikely that I will use it in the future, so I am putting it up for sale. I will wrap it in cushioning material to prevent it from losing its shape during shipping. #Exoterra #GlassTerrariumNano #Backboard
