Apart from the Metal & Rubber line, there is probably no pen model that uses soft rubber as the pen body. And perhaps only the Starwalker pen line has creative and unique designs like this version. A rare material in pen processing, but rubber is completely new, breaking away from the rut of original designs.
Rubber not only makes the pen special, it also helps the user feel more comfortable holding it. The pen is soft but the core inside is hard and durable. The rubber coating creates elegant checkered patterns. However, rubber is also quite "difficult" in terms of preservation, this material will not be able to withstand places with too hot temperatures or strong external forces.
The pen also has a 14K gold nib crafted in size M for both signing and writing.
