I have the bad habit, always losing my pen, so I decided to buy me this "value pack". First of all, the package was complete, so it was really 50 pens available. However, the colors are not mixed evenly. I barely had red and orange ballpoint pen, which I personally find but not bad. However, if you absolutely want to have a certain number of pens of one color, which should maybe consider buying no mixed package. Now I have not tried all the pens, but I have already used all function properly and are comfortable to hold, so you can also write longer so. Merely always summer when you sweat, the ballpoint pen to slide a bit in hand. But I personally do not have any pins found, where this is not so. For me, absolutely great from the price-performance ratio.
