I purchased these pens because they were gel ink and the tube was grippy which is great since I do a lot of writing for work. I was extremely disappointed when after writing 2 pages (no exaggeration) the ink started to fade as I was writing. Then the pen just stopped writing altogether. No ink would flow out of the pen. I attempted to scribble on a piece of paper hoping it would start to flow again but it did not. I thought it was maybe just the one pen I was using possibly being defective but then the same thing happened when I tried to use another pen from the pack. I highly recommend purchase another brand/type of pen that’s actually known for its quality. I got excited for these and was quickly let down.
They didn’t write well. Seemed like there might have been air bubbles because i would be writing and then nothing . I would scribble and get the ink going again and then would continue writing and then nothing . I spent more time trying to get the pens to work than actually using them.
