Bests & Worsts Reviews from Amazon

Bought these pens for my planner about a month ago (April 2016), and the pens have been holding up very nicely. The black pen is used the most often, but all the pens have about the same ink consistency. Pros: - Pen retracts by clicking the pen's pocket holder clip. No need to uncap the 'eraser' end to erase ink. - Colors are vibrant, except for the black (more like a dark grey). - Ink consistency is like regular gel pens. Not very much pressure is required to write solid lines. - Intentional erasing will almost completely erase markings. See attached photos. Cons: - Hasn't happened to me, but I heard that leaving the pens/written materials in a hot car will make the ink disappear. But I also heard that putting the previously heated pen/ink in the freezer for a while will make the ink reappear. I've been mindful of this, and been careful not to leave my pen set in my car.
