I purchased a new nib and immediately found out there was a problem. The nib was scratchy and dug into the paper. But this isn't a one star review because of what happened next. I e-mailed Wonder Pens and heard back from them right away. After having me check a couple of things it was determined the nib was bad. A couple of days after sending the e-mail a new nib (tested before mailing) arrived in my mailbox, postage paid. Now I have a great nib. Because of the great customer service I would highly recommend this purchase.
