The TWSBI VAC Mini fountain pens combine a high-quality vacuum filling mechanism with a modern, transparent design, in a easy to carry mini format, all at a surprisingly affordable price! Simply pull up, push down and your ink is filled, ready to go.

TWSBI fountain pens are loved for their high quality and affordability, offering advanced filling mechanisms normally reserved for much more expensive fountain pens. The VAC Mini features a modern, eye-catching design, with a transparent body that shows off the pen’s inner workings. Its high-capacity vacuum filling mechanism is easily operated by twisting the knob at the end of the barrel counter-clockwise, pulling back the plunger, then submerging the nib in ink and pushing down the plunger to create a vacuum that sucks the ink up into the barrelno need for cartridges or a converter!

The pen also features an ink shut-off valve, which seals the ink chamber when the knob is fully tightened, preventing the pen from leaking if you take it on an airplane. To open the valve and allow a continuous flow of ink, twist the knob counter-clockwise until it is loosened, but do not pull back the plunger.

This VAC Mini features an updated valve design for improved ink flow when the knob is loosened compared to the original Vac700.

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. Hence, these pens 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. Pleae folow the instructions that accompany the pen.

Please note that this pen uses bottled ink which is not included with 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.
