If your case gets wet, let it air dry naturally away from heat sources (radiators, direct sunlight).Wipe off dirt with a soft, damp cloth. For deeper cleaning, use a leather-specific cleaner. Apply a leather conditioner every 6–12 months to keep the leather supple and prevent drying or cracking.
Do not machine wash or dry clean. Do not fold the case tightly - this may cause permanent crease.
