For the amount of money spent on each of these, I expected better.
The black pens will not stay open so I can write with them. They keep retracting so only a tiny tip of the ink cartridge sticks out to write with The white one appears to be working ok. I've bought two of the black ones hoping I would get one that works properly. For the amount of money I paid for these, I feel I should be getting one that works and has enough ink in it to last longer than a few days. I've had to purchase a few pen refills within a short time after I received each pen. I do find the stamper to be of good quality and like the fact I can carry it in my pocket without it taking up to much space, since I do have quite a few things I have to carry in my pocket for my work.
