Hi, is anyone else seeing this problem (pics below) with a black-finished Monteverde pen? This one in the pics is a Monteverde Intima in Volcano Grey acrylic. The pen is about a week new out of the box and the only ink it has seen is Diamine Graphite (which goes well with the acrylic and black finish). The flaking looks like corrosion, it is not wear of any sort. Definitely defective. Thanks, David
