We don’t cover a lot of toothbrushes on Cool Material. This is partially because most people are far more concerned about what their dentist has to say on the matter than what we do, but also because most toothbrushes are just plain boring. Yumaki’s toothbrushes are anything but boring. Yumaki toothbrushes are available in a multitude of plastics (PP and PETG), colors (handles and bristles) and pressed wood (with and without skateboard grip tape), and each has a hole in the end for a single tuft brush or interdental pick. Leave it to the Japanese to make even the toothbrush cool.
