We asked over 2,000 teachers in our Facebook groups and pages what their favorite pen is and their favorite was Paper Mate Flairs, followed by Paper Mate InkJoy, Pilot Erasable Frixion, Pilot G2 Gel and Bic Cristal Xtra Bold. Below we have created a list of budget-friendly pens available on Amazon with our suggestions for teachers. This site is updated daily, but prices and availability are subject to change at any time.
