Soft Grained leather
Product care & refills
Leather is a natural material and you need to care of it. To start with, leather is sensitive to water. It is therefore important to avoid prolonged contact and to dry your briefcase or wallet by dabbing it with a soft, light-coloured, cotton cloth if it gets wet. Similarly, leather is sensitive to heat, humidity and strong sunlight. It is strongly recommended to keep any leather items away from heat sources. And to clean the leather, do not use any wax or waterproofing type of maintenance product, but a slightly damp cloth made from a neutral colour, soft cotton.

Tanning with diamond powder

For the new edition, S. T. Dupont has once again used the unique diamond-powder leather tanning process that has been our signature since 1929, on a very contemporary grained leather. This distinctive process gives the leather amazing shine and resistance.


S.T.Dupont is breaking new ground by becoming the first luxury leather goods brand to incorporate a device called D-Gital into its “LINE D SOFT GRAINED COLLECTION” wallet lines, indicated by the presence of a specific card. This innovative technology, patented and approved by the German certification laboratory TÜV, is a specific material made from an alloy of nylon and metal integrated into the lining of the card compartments. It blocks the signal emitted by the RFID system and makes it impossible to hack.
