Best pen I've bought in a while
Got the medium nib. So glad I bought this pen over the Eco. The pen moves so smoothly on paper. Absolutely love it.

Great, great fountain pen!
Right size, right weight, feels good in your hand, runs smooth and the stub nib at TWSBI is perfection. (And the reason I discovered TWSBI - now I have five of these.) Great service, fast, clear, quick! Thank you!

One of the best if not the best, most perfect fountain pen I have ever used. The nib is so smooth and the grip is so comfortable. So glad I bought this LE pen!
