Twsbi Eco Slate Blue Fountain Pen is a stunning and reliable choice for both beginners and seasoned fountain pen enthusiasts. The TWSBI ECO fountain pen boasts an incredible value with its piston filling system and affordable price. Like many other TWSBI fountain pens, it features a crystal clear acrylic barrel so you can see your ink level, and a slate blue cap and finial. The pen cap has an inner cap to ensure a perfect seal when stored away. It is completed with black onyx trim and a black stainless steel nib. 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.
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.

In general I like Click pens and especially their nibs. This one I bought for the beautiful acrylic. I am using it with a Diamine Green Ivy Shimmer ink and nib is performing very nicely.
