Pentel Slicci Gel Ink Pen - 0.25 mm - Rose Pink Ink

As far as needle-point micro gel pens go, the Slicci will always win in my heart for smoothest writing experience, no scratchiness or stuttering of ink flow. The rose pink color is also really unique - it's bright enough to pop as an accent color amidst my monotone notes, dark enough not to cause eye-strain like lighter pinks.

The only losing points of the Slicci: 1) tiny barrel is uncomfortable for marathon study sessions, 2) tiny barrel = very little ink, compared to the Hi-Tec Cs.
