Zebra PenZ-Grip Gel Retractable Ballpoint Rollerball Pen, Medium Point, 0.7mm, Black, 12-Count (42410)

I love this pen, I bought a box in black and now red. So smooth and flow-y. Some people complain that it suddenly clogs when the barrell is full. This DOES happen sometimes but the problem is easily remedied by letting the pen sit in really really hot water for a few minutes. I think sometimes the roller gets a piece of dust or other obstruction which causes it to stop rolling. I love these pens!

I used to buy these exclusively. Up until this most recent purchase these pens had been great but not this box. This box of pens were junk because they do not write clean, the ink intermittently flows to the paper and the ball feels like it seizes rather than continuously rolls as it is supposed to. Very frustrating because I have been buying these for year but I'll not buy them again.

Super writing tool for the sensitive and everyone else. These are the original, no knockoffs. They write really smooth; no paper scratching here. And they write medium bold which satisfies most writers — yes, there are a few of us left. And these are the pens for us. Love that red!!

I bought these pens as a gift for my wife who had an old one of these as a favorite pen. I don't know if the product changed or the ones we received were just old or damaged by storage conditions, but they barely write, even when pressed hard. I would have tried to return them, but in frustration we threw a couple out thinking innocently that the problems were with individual pens, but it seems to be the whole pack.

I wish I could give these pens a good review - I think they are so nice looking, they have a good grip, and I like how they write. However, I consistently have difficulty actually keeping them writing. Multiple pens in the pack have abruptly given up working within a week of being purchased. I can see there is plenty of ink in the barrel, but nothing comes out. Very frustrating.
