But my problem with this pipe is the cork granules is the fact. Some people have to have a habit even in rain and snow with the dog out. This may be due to the fact that the dog has to be solved, he likes to spend his time outdoors and / or as a service dog in the avalanche guard, the police or as a guide dog is traveling.
My cork granules behaves not particularly useful when it comes in contact with moisture and to mention the hygiene once completely.
How much I miss my old pipe which beads of the same material as the pipe itself was.
