Clean-brush / Brush design


It’s really annoying that those paint drops splash everywhere when we paint the wall, especially when we dip the brush in the paint. Our design solves this problem. Inspired by a pen, we store the paint in the handle of our brush, which keeps our house clean and makes it an environment-friendly way to replace the using of paint bucket.
