Review on Vitoler Retractable Erasable Gel Pens - Make Mistakes Disappear, 10-Pack (5 Black & 5 Blue) For Drawing Writing Planner And School Supplies by Sade Tucker

I love the pen colors and it erases very well; they just don't last long. It's too bad because I really like these pens. I use them in a planner to make it a bit more fun to write in and I rotate colors. Three stopped working pretty quickly. My best guess is I got the equivalent of writing one page (8.5x11) front and back at most. Probably less. I don't know if the ink dried out (I tried wetting the end) or if these ran out of ink. I've taken the pens apart but can't see the ink levels as the ink tube is opaque. Of course I'll continue to use until they all stop writing, but I wouldn't buy again.
