It’s not irrelevant on what kind of surface you keep your soap. The heartwood of pine is a perfect material because it is naturally antibacterial. Antibacterial means that it is hygiene because bacteria can not grow on top of the wooden surface. Our plates have a hole that enables the soap to dry between uses. That also increases the useful life of the soap. Take notice that our soap plate can also be used under shampoo and conditioner bars in the bathroom.
