The TWSBI’s Precision series is a range of all metal pens with hexagonal barrels. This TWSBI Precision fountain pen has a blue aluminum body, cap and grip with stainless steel trim. It is equipped with a stainless steel nib. It's comes with a benchmark piston ink-filling mechanism and has all detachable parts. The pen holds a good amount of ink and there’s a small ink window so you can see how much ink is left. It comes in the same packaging as the Diamond and Vac pens, including a wrench and small pot of silicone grease. It also features a chrome trim and a stainless steel nib for a smooth writing experience. With its classic and timeless design, the TWSBI Precision Fountain Pen is a great choice for anyone who values precision and quality. 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.
With a history of more than 40 years of manufacturing, including producing high-end pens for other brands, Ta Shin Precision decided to start selling under their own brand, TWSBI. The name TWSBI is made up from TWS and BI. ‘TWS’ is the reversed initials of the phrase ‘San Wen Tong’, translated Hall of Three Cultures, and ‘BI’ literally means writing instrument.

Waterman expert is an amazing writing tool (only one good pen needed). And online mantra provided me that good product. They provided me an ink converter and an additional complimentary pen pouch also. Thank you onlinemantra.
If these refills could be offered more often at larger quantities and better prices then no need to look further.
Excellent fountain pen, fine nib. Receive the package properly, well packed and on time as informed. Thanks to Online Mantra.

The Pen is of excellent build quality and the weight is nicely balanced. The only downside is that it is a bit top heavy. Other things are OK
