PRE-ORDER POLICY AND DELIVERY TIME

Estimated Dispatch Date:

T&Cs: Orders that contain pre-order item will not be shipped until all items are available. If you prefer not to wait, please order pre-order item separately.

 

The TWSBI Obsidian combines aesthetic refinement with mechanical precision, showcasing a distinctive dark grey and black marbled acrylic resin barrel accented by rose gold plating throughout. Its rose gold-plated stainless steel nib provides writing characteristics aligned with TWSBI's 580 specifications, delivering reliable performance across various writing styles.

The pen features TWSBI's signature piston filling mechanism for efficient ink capacity and smooth operation. A transparent ink reservoir window enables quick assessment of ink levels during use. Whilst the cap is physically compatible with posting on the barrel, TWSBI recommends refraining from this practice to prevent potential scratching or wear to the pen's surface.

 

The TWSBI Obsidian showcases an innovative injection molding coloring method that produces distinct patterns and hues. As a result, each pen is one of a kinda and we are unable to accommodate any special requests.

TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile. Please follow the instructions that accompany the pen.

TWSBI

Inspired by writing

After 50 plus years as an OEM manufacturer for different global brands, Ta Shin Precision decided to start selling under their own brand, and thus TWSBI was born.

TaShin Precision has over 50 years of experience in manufacturing with plastics and metals. Early products ranged from toy lego parts to high end writing instruments. This knowledge trickles down into every product TWSBI has to offer.

TWSBI's name stands for the phrase "Hall of Three Cultures" or "San Wen Tong" in Chinese. The character "Wen" translates into language and culture. The phrase "San Wen Tong" also brings to mind the Hall of the Three Rare Treasures created by Emperor Qianlong as a memorial to three great masterpieces of Chinese calligraphy. The initials of the phrase "San Wen Tong" was reversed and thus turned into "TWS". The last letters "Bi" was added with its literal meaning of "writing instruments". Thus combining the two segments, creating TWSBI.

To achieve their mission:
