The pen’s barrel to the cap, fusiform design in one piece

In architecture, there has been a tradition and constructing technique of creating curved surfaces with geometric plane. This edition of writing tool has a curved surface or "fusiform" (spindle) shape, derived from the same architectural concept. At the same time, around the joints of the concrete plates, natural traces and marks from usage will appear; the more you use them, the darker the colour will be, and the smoother the touch will get. It is worth mentioning that, for the overall spindle-shaped aesthetics, the stainless steel cap is especially contracted at the top, which is a rare design for writing tools in the market. It must be manually processed one by one, which is time-consuming and labour-intensive.
