Tom's Studio The Wren Spare Ink Reservoirs – Pack of 5

Tom's Studio Spare Ink Reservoirs are replacement cotton core inserts designed specifically for The Wren pocket pen. These high-absorbency cores hold fountain pen ink efficiently inside the pen barrel to maintain a steady flow to the writing tip.

Dedicating a separate reservoir to each of your ink shades allows you to switch colors quickly without needing to wash out a single core, preventing cross-contamination and keeping your colors pure. Pair them with reservoir containers to keep your extra ink palettes loaded and ready to swap into your pen frame.
