### ⭐⭐⭐⭐⭐ Best gel writing pens
*by A***E on December 29, 2025*

LOVE THESE PENS! I am a grad student studying for board exams and constantly making written notes (I am an old school learner). These pens do not bleed or leak regardless of the writing surface. They write smooth on graph paper, cardstock paper, construction paper, etc. As a bonus, the wide pen makes the grip comfortable for extended writing periods ( like 3-4 hrs or more). Those who have RSI pain related symptoms shod also consider these pens.
