Use a good quality leather conditioner or protective spray to treat the product to increase its durability. Regularly clean leather with a soft brush or cloth, regularly air out leather, and where possible do not get leather wet. Blot away water or moisture as soon as possible, do not immerse leather in water to clean, do not dry wet leather with artificial heat like a radiator or hairdryer, do not machine wash leather, do not tumble dry leather, do not iron leather. Keep out of direct sunlight to avoid fading and avoid wet weather. Marks and variations in the leather are not considered a fault but are inherent to the natural beauty and uniqueness of the leather. When not in use we advise to store your St. Agni product in its protective bag and we recommend to continually treat it with a leather conditioner to keep it hydrated for a long life.
