Stifflexible is inspired by an ancient binding system used in an old book shown to Giuliano Mazzuoli in an old florentine library, where the hardcover was at the same time flexible allowing for an easy consultation. This is in fact where the name Stifflexible comes from, that is "stiff but flexible."
The idea to make a hardcover that works like a soft cover allows for an original product in a contemporary "key" with an attention to tradition. The inside is a pocket in black paperboard where small documents can be inserted.
The pocket is finished with a flap that can be used as a bookmark.This is another distinguishing factor of Stifflexible.
