Blue ink. Fine tip. No arguing about whether it's navy or sky. Twelve UNI-BALL Air rollerballs in blue, fine nib, the sort that writes clean on a student's worksheet at 8:45am without the pen dragging. When the supply closet is down to one half-dead Bic and the term starts Monday, this box keeps the pens flowing. No smudging, no skipping, just twelve reliable blues when you need them
