Collection: Pen tip adjuster

Fountain pen nib adjustment
Pen Doctor Fountain Pen Writing Instrument

At Pelle Penna, we sell fountain pens that have been supervised by our pen doctors (pen nib adjusters).
A pen doctor's job is not just to supervise and adjust nibs before they are sold.
If you are using a fountain pen and it starts to become difficult to write with or you notice some issues with the pen, the Pen Doctor will adjust the nib for you.
(*Nib adjustments available at the online store are limited to "Leonardo Officina Italiana" and "Diplomat.")

Introducing the Pen Doctor

  • Yoshito Nakatani

    Joined Diamond Co., Ltd. in 2001.
    He worked in sales at department stores and other retail outlets before moving into pen nib adjustment.
    He then trained at an Italian brand and became a pen doctor specializing in Diamond Co., Ltd.
    Currently, we hold pen clinics all over Japan and also inspect fountain pens.

  • Kazuyuki Doi

    After working at a stationery store for seven years, he joined Diamond Co., Ltd. in 2016.
    He trained under Pen Doctor Nakatani and made his debut as a pen doctor in 2024. While inspecting fountain pens, he also works with Nakatani in pen clinics across the country.
