This design is made of soft suede and brown vegetable tanned Italian grain leather. Suede should not be greased in any way or excessively moisturized. You can apply a dedicated suede cleaning brush. Do not allow the leather to be drenched, this can lead to dyeing clothes and damage. If the leather does get wet, wipe it quickly using a dry cloth. Do not use a hair dryer or heater. Do not allow contact with perfume, chemicals, etc. Do not expose the bag to excessive sunlight as this may lead to permanent discoloration.
