Portable Brush improves the protection of the brush head when travelling on the go by adopting the design of a pen with a pen cap. When in use, the cap can be securely placed on the other end of the brush instead, thus increasing the length of the whole brush for a better grip, just like an ordinary brush.
Using traditional Chinese methods to make the brush head, the brush can be used for both paintings and Chinese calligraphy. The brush head can also be replaced easily when it is worn out so that one does not have to replace the entire brush. This allows the user to change the brush head for different styles of creation, without changing how the familiarity of the grip feels.
