List of the stationary I've grown to love in my time of being a student, that I would reccomend a million times
Some of the smoothest affordable rollerball pens I've used! I'd reccomend getting a size 0.7 and a size 0.38, as you get variety with your line weight, and thinner pens are hard to come by.
PILOT G2 Premium Refillable Retractable Gel Pen
Super smooth lead and writing experience! The size isn't too big, nor too small, and the lead! Glides like butter.
