I don't know about you but here at Bosca we still love to write. Whether it's number 2''s or a favorite Parker or Faber-Castell this is where I know my writing instruments will be. This one is square. It is wrapped in one continuous pieces of leather, and the corners are handbeveled. The linig is a dark synthetic with no rough edges anywhere. Nappa Vitello by Bosca is a super-soft and smooth Argentine cowhide with an all-analine finish.
