Sometimes the pen needs to be pressed a little harder than expected but they work. that half of the pins are silver if the chosen option was black. The darker ones will stand out more from my workplace, these silver ones are already lost for me. The description doesn't say half of the pins will be silver. Edit after 1 week: They definitely hit or miss on how well they write. Some work better than others. Some are very sketchy and generally bad at writing :/
