Genius Pipe G-Stone 3-Pack
The G-Stone is a ceramic sponge that is completely inert. This means it will not emit any smoke or vapor by itself. Your concentrates are absorbed into the stone and once the temperature is hot enough, the concentrates vaporize inside the stone. Since there is no water to filter out taste, together Genius Pipe and G-Stone give you an undiluted tasty hit.
Users can now enjoy the full flavor of their concentrates without a large rig, water, hot nail or torch.
