Have you ever felt that you would like use Pole Moxa even last 2cm? Is there any ways to solve it? If you think that way, you are a right person(?).
Some people call you as stingy, but people are programmed to feel guilty for wasting. It is normal to feel it. The Bamboo is the perfect solution for your guilty feeling.
Put new pole moxa from bottom of bamboo and push it. Then old short pole moxa appears from top of Bamboo. Just stop the habit to throw the short pole moxa after you buy the bamboo.
