"The Best Teacher in the World" is the inscription on the book-shaped case containing Montegrappa's new creation. Inside is a writing instrument that not only provides the pleasure of writing that one can expect only from an Italian artisanal product but has also been modeled after a historic pen that was popular in classrooms throughout Italy over eighty years ago. All Montegrappa writing instruments are guaranteed against any manufacturing defects for 24 months from the date of purchase. Any part of this pen that shows even the slightest manufacturing defect, as determined by our authorized customer service, will be repaired or replaced under warranty. To benefit from the international warranty, simply present the correctly filled out international warranty certificate, stamped and dated by one of our authorized dealers, to one of the Montegrappa service centers.
