Embodiments of the disclosure can include writing instruments, nibs for writing instruments, and methods of making the same. In one embodiment, the writing instrument includes a reservoir; an ink solution comprising a pigment, the ink solution being housed within the reservoir; a nib disposed at an end of the reservoir and plugging an opening of the reservoir such that the reservoir is closed, wherein a tip of the nib extends outside of the reservoir; and a filament extending within the reservoir, the filament being in fluid communication with a portion of the nib within the reservoir, such that the ink solution travels along the filament and through the nib, by capillary action, wherein the nib and filament are formed such that no more than 50 percent of the pigment present in the nib and filament flow into the reservoir outside of the nib and filament when the writing instrument is stored with the nib up for a period of one day.
