I was inspired by a Dragon Boat Festival tradition called Egg Standing because as a kid, I never succeeded in making an egg stand on its end. Now, I made the end of the toothbrush in a curved shape and put lead inside of it to enhance its center of gravity, which easily helps make the toothbrush stand. While the toothbrush stands, unnecessary water flows down along the handle from the head, which helps prevent mold and bacteria from breeding in the fur scrubbers. It's also a telescopic toothbrush that is easy for you to put anywhere as you please.
