Pilot FriXion Clicker Pens with Refills, Fine Point, 0.7 mm, Green Ink, 8 Count, 2 Pack

Pens are great! I have been using them in all colors for several years. The only negative thing about them would probably be a concern only to a teacher. When I first started using them I made a bunch of notes on 3 x 5 cards. When I put them thru a laminated, the ink disappeared. That was a little disappointing . I especially like these pens for my planner. They come in a variety of colors so I can make certain things stand out. Also, if plans change, just erase. No more crossing out or using white-out.
