0.3mm synthetic tips that write cleanly across journal pages, planners, and correspondence-weight papers where heavier markers would ghost or feather. Water-based pigment ink dries quickly enough to prevent smudging when you flip pages or layer handwriting, while maintaining the kind of lightfast permanence that keeps journal entries legible for years.

Japanese manufacturing ensures consistent tip performance and ink flow. Each pen's barrel matches its ink color, practical identification when you're working quickly through multiple colors in detailed spreads or color-coded notes. The synthetic tips maintain their shape through extended writing sessions without splaying or losing precision.

Choose the Primary Set for everyday essentials: black, red, blue, green, brown, and dark grey cover standard journaling and note-taking needs. The Jewel Set expands your palette with orange, lavender, pink, burgundy, navy, and teal, colors that add visual interest to bullet journals and planners without the aggressive saturation of fluorescent markers. Both sets provide smudge-resistant, non-toxic ink that performs reliably on papers too delicate for alcohol-based markers.
