Most manufacturers offer a range of nib sizes from ultra extra fine to double broad, but we know that sometimes one wishes for a truly unique experience of pen to paper.


For those interested in a customized nib, we work with Mike Masuyama, who offers both tuning and customization. Given his extensive experience making adjustments for myriad brands of fountain pens, Mike can adjust nibs to write more narrowly, with different ink flow, or even with new line variation.


Fill out the form below to start the process, which includes shipping your pen to us for Mike to modify; in general, the process can take four to six weeks, depending on Mike’s capacity.
