I love this pen because I have a tremor in my right hand, and after buying numerous pens trying to find one that works well, this one works for me. The shape of the pen with the rubber part helps anyone with a shaky hand. I wish there was a way I could purchase more black refills, as I use it to write in my daily journal. The other colors are okay but nothing to get excited about. I just ordered 6 more of these, because I need to keep them in stock.
