A toilet brush that prevents microplastics from flowing out of the toilet drain.　 * The toilet brush (for stand-alone) cannot be used on the stand of the toilet brush set. Toilet brushes on the market are mostly made of plastic. In some cases, the brush part deteriorates and comes off, spilling out of the toilet drain and causing microplastics. The toilet brush, which is made of 100% natural materials, is made of sisal, so it is a material that returns to the soil. It is as soft as plastic and can be scrubbed firmly without damaging the toilet bowl. It also comes with a cotton string for hanging, and it can also be used in the interior of the toilet. * No two natural woods have the same grain, and each one differs in color and mottled characteristics. In order to protect forests, we ask that you enjoy and understand the unique taste and individuality of natural wood.
