There are various toothbrush or toothpaste products on the market that emphasize oral health, but everyone ignores the importance of mouthwash cup hygiene. When the traditional mouthwash cup is placed upright, it is easy to hide dirt and dirt due to the accumulation of water at the bottom, which becomes a breeding ground for bacteria. Brushing.Know subverts the experience of using traditional mouthwash cups. A magnet is placed on the front of the cup holder. The mouthwash cup with magnets at the bottom can be adsorbed upside down to let the remaining water droplets flow out and keep the cup dry and not easy to breed bacteria.
