TWSBI ECO is TWSBI’s most affordable fountain pen model and reflects the company’s long history of pen manufacturing. TWSBI began as an OEM manufacturer for Western brands before establishing its own brand around 2009, drawing on approximately 50 years of pen-making experience and feedback from fountain pen enthusiasts. The name TWSBI is derived from ??? (San Wen Tong), or the Hall of the Three Rare Treasures, associated with Emperor Qianlong’s appreciation of three great Chinese calligraphy masterpieces. “Bi” refers to writing instruments, giving the brand its name. Known for its transparent fountain pens, TWSBI continues to create pens that combine functionality, durability, and the enjoyment of seeing your ink in action.
