The Maths is the flagship bag of Craie.  It's a mixture of canvas and leather making it the ideal all-day bag. The Poetry Bag is an off-white cotton and polyester jacquard, with multicolored vertical lurex threads, and the fabric is made in France.

The flap is a gold sanded leather made from goatskin leather with a metallic leather film and sanded in the spirit of Galuchat.

Reversible, your Maths turns to be also upside down: the flap is then in beige velvet and the body of the Peach cotton bag. Modular, this bag is worn on the shoulder but also in a backpack thanks to a ring that, passed over the shoulder straps, creates straps. It closes with small snaps hidden behind the buckles. Available in Mini or Maxi format. Homemade.
