TWSBI is a modern brand inspired by writing. The company has many years of manufacturing experience and the pens are loved for their affordability, advanced filling-mechanism and unique finishes. TWSBI pens are high quality, precise writing instruments. They hold much more ink than cartridges and you can draw ink directly from the bottle, no converter needed. Their transparent barrel shows how the pen works and it’s fantastic to see how beautiful your ink looks inside. TWSBI fountain pens can be disassembled and reassembled, allowing the user to fully experience every aspect of the fountain pen. They even come packaged with a wrench and silicone grease that is very useful for long term maintenance. These pens are designed and manufactured by Ta Shin Precision and are a Red Dot design award winner.

The TWSBI ECO-T is an economical fountain pen that holds just as much ink as the Diamond 580 but has an affordable price that is appreciated by the first-time fountain pen user. It has a slightly more pronounced grip section and the cap and end cap have a rotary triangular shape design.
