This is my absolute favorite...

This is my absolute favorite pen for math classes! The 0.7 mm refills are very smooth, making it easy to write for a long time without hand fatigue, and the shade of blue in the ink is bold and easy to read. I prefer Frixion pens over pencils for math since they actually erase more cleanly as long as the paper isn't too thin/cheap.

The metal body of this pen was worth the extra cost to me since it adds just the right amount of weight for a good balance in the pen, as well as needing less pressure to write. The knock mechanism in the clip is fairly sturdy, and the eraser hidden under the top cap comes in handy when I don't have my block-style Frixion eraser around. Refills are easy to change out just by unscrewing the silver metal tip. Be careful when putting it back on though, the spring in the front can send the tip zinging across the room if not screwed in before you let go!

Really nice writing instrument, I'd definitely recommend this to fans of the Frixion line who like a heavier pen.
