This design is made of black vegetable tanned Italian grain leather and soft suede. This leather should not be greased, a wet microfiber cloth can be used to clean it. After this treatment, wipe with dry cloth or paper towel. 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.
