The Cleaning Plug for Glass Water Pipe is a simple tool to help keep your water pipe clean. If your pipe is equipped with a removable downstem or diffuser, remove it and clean it separately. The Cleaning Plug for Glass Water Pipe slides into the ground joint in the reservoir, just like a bowl or a banger. Leak resistant, yes. Leak Proof, no. Hold the plug in place (or pick up a keck clip in your size), cover the mouthpiece and swirl your cleaner. If you prefer a soak, leave it in a sink. Hand Made in USA
