Early Krone luxury pens harkened back to the Parker Duofold button filler. Our Krone Hyperbole is one of those pens, which we had fully restored with a new ink sac at Krone's factory. The nice thing about these preowned luxury pens is that Krone guarantees them for life. So when the sac finally gives out, just send it back to them for a free repair! We like how this model looks like old-fashioned hard candy. The silver trim is nice, too. You will write a nice medium line with a little feedback...even though the 18k gold nib is marked XF for extra fine. 11.7cm capped.
