These pens have black ink. They are so handy to have on busy days when you are on the run meeting people and going to business events! I personally make sure each one works when I receive them from the company, and again before I ship them out to you! All you have to do is pull it apart where the two metal pieces meet up, and your pen is ready to write! At only $1. each, these always go fast. Get one of each color for your wardrobe!
