My go-to for years
My go-to pen for years. No skipping, no ink blobs, just clean, thin (0.28) lines through and through till the last drop of ink. Best quality pen I have used and very difficult to find a good thin pen like this! Sleek and well made.

Great pen!
I usually use a 0.38mm tip so it took me a while to get used to the 0.28mm tip but now I use it all the time. The pen writes smoothly and dries quickly.

Product below quality
The ink quality is not good. May be it is dry. With 0.28 tip i wanted to try it. It has a feeling like when the refill is about to finish

Süper ince yazı
0.28 kalemin en zarif hali. Hafif ve pürüzsüz yazmak bu kadar keyifli olmamıştı
