One word describes the TWSBI Eco: smooth. I love this pen because it embodies that word. The Eco’s design is modern and sleek while its feel is consistent and effortless. All these factors make this pen incredibly popular. This pen is a refined feat of engineering that has been TWSBI’s calling card among enthusiasts. Adding to the allure is the demonstrator effect. Demonstrators are uncommon in the pen world and you won’t often see one that is not a TWSBI.
I rarely see white pens so I decided to purchase the Eco with a fine nib, white-barreled model. I have drained the ink well twice now since I bought it a month ago. I wish I had bought one sooner. I’m surprised by how much I love watching its inner workings.
It’s easy to get distracted as this pen glides. The nib is flexible but firm, with just the right amount of spring. There’s no hitching on paper or rough edges. The internal converter draws ink quickly. TWSBI even provided a little bottle of silicone to help maintain the converter’s moving parts. The ink distribution is perhaps a touch too wide at times, but it may just be my ink. You can use an ink flow test, as shown below.
The pen is well balanced with the cap posted or without. The rubber ring it sits on does not have the tightest grip. But, you do not need to worry about the cap rolling or popping off as you write.
Sometimes cleaning your pen can be a hassle, as I mentioned in my last post. I was concerned about getting the nib back on the thin feeder. I had no reason to be concerned. The nib and feeder easily came out of the barrel and perfectly seated back together taking the guesswork out of properly aligning the nib to the feeder.
The TWSBI Eco is special. Not just its design, or function, but TWSBI’s commitment to quality. That will make me into a loyal enthusiast. I cannot wait to buy another. What is your favourite pen?
