The Portable Brush is based on the design of a pen with a pen cap to better protect the brush head during transport. When in use, the cap is securely placed on the other end of the brush, increasing the length of the whole brush for a better grip. The brush head itself is made with traditional Chinese methods and can be easily replaced when it is worn out. This allows the user to change the brush head for different stroke effects without changing the overall familiar grip of the brush.
