I recommend Appelboom
I wanted a new fountain pen in order to try an oblique medium nib. The pen I chose from Appelboom's site was in stock but not with that nib size, so I sent photos of me holding a pen, and Mr. Joost Appelboom had their nib specialist, Anabelle Hiller, grind the nib to the size I wanted, adjusting it uniquely for how I hold my pen. The wait for this service was approximately two weeks. Appelboom sent me tracking, and once the pen left Holland it arrived to the U.S.A. in a few days, beautifully boxed and wrapped. After writing a few sentences it became my favorite; I have dreamed of a pen like this. I have not found any other pen seller with their own nib master for customizing pens. Appelboom also offers their nib master’s service for free to “Tune & Smooth” the nibs of many fountain pens they sell. It’s a choice one makes at checkout. The pen I bought would have cost me substantially more in the USA. I was impressed that the director and owner of the company himself, Mr. Joost Appelboom, e-mailed me back and forth to help me get the nib I wanted. I like to purchase from a company with a passion for its own product, and this is evident in Joost’s many pen videos. I like watching him interview pen specialists from all over the world on his YouTube channel, “Appelboom Pennen.” I looked online at many pen sellers. Appelboom stood out as the best choice because of its large selection, its nib-customizing service, its excellent prices and reputation, its newsletter, its website’s helpful information sections, as well as Joost Appelboom’s well known presence in the international pen community. My experience with Appelboom has been superb, and I recommend this company heartily.
