You will be amazed at the duality of this pencil: the more it wears out, the closer it comes to germinating life into a new plant. When there is very little left, you can simply plant the piece of pencil as if it were a seed. With this pencil, you contribute to an effort to support the growing of herbs that can be found in a home garden. Each pencil contains a different type of seed: parsley, basil, perilla, mint, sage, anethon, thyme, and clover.
