After the longest pen show hiatus imaginable we are excited to finally be returning to the fun! The very first show since the beginning of the pandemic for us will be the Dutch Pen Show hosted by Appelboom, P.W. Akkerman, La Couronne Du Comte, and the Sakura Fountain Pen Gallery. No appointments necessary, I will be offering the usual nib grinds, repair and tuning. For a more thorough list of the services I currently offer please check the Appelboom Nib Customisation Page. We are hoping that John Sorowka will be able to join me that day, but it is uncertain yet what travek restrictions between the UK and the Netherlands will allow. So much has happened since the last show we attended, and I am very grateful to finally get back to it and catch up with everyone there. Please be aware that this will be a masked event and participants and visitors must be able to prove they have either been fully vaccinated, have valid proof of recovery , or have a negative test result of a test taken less than 24 hours before entry to the venue. https://www.opuscineris.com/events/dps2022 monthly 0.5 2022-05-23 https://www.opuscineris.com/blog daily 0.75 2025-09-19 https://www.opuscineris.com/blog/plan2026 monthly 0.5 2025-09-19 https://www.opuscineris.com/blog/fountain-pens-and-the-netherlands monthly 0.5 2025-02-09 https://images.squarespace-cdn.com/content/v1/6184268fe2bb0a70113befae/98005bf5-ae7e-48f1-b6f3-24e06ff6522e/DPS-2019-29-scaled.jpg Blog - Fountain Pens in The Netherlands - Make it stand out Dutch Pen Show 2019.
