Nama shirasu
Penne19 is one of the 713 brands in Inktend's built-in ink catalog.
Paper & pairing
As a near-neutral tone, it reads as professional and safe for anything from journaling to signatures. This ink will behave predictably on most fountain-pen-friendly paper. Cheap, highly absorbent paper (standard copier paper) will dull any ink's saturation and can cause feathering or bleed-through with wetter nibs.
About Penne19
Penne19 is a small stationery and pen shop in Fuji City, Shizuoka Prefecture, Japan, describing itself as 'a stationery shop that deeply loves pens'. With a retro atmosphere, it sells glass pens, custom fountain pens, and curated inks, and releases original and collaborative inks, including flavors made with Tono&Lims, often themed on Mt. Fuji and local specialties like whitebait.
Storing and using the bottle
Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight: most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
