Please accessories are made with natural leather, hence you should treat it with care and tenderness while cleaning.
Clean the dirty surface with a swab lightly moistened with lukewarm water and soap. Periodically, you can treat the leather with special leather cleaning creams. Do not use solvents (e.g. acetone) – they may damage the structure of the leather.
Remember, that mechanical damage, abrasion, and scratches resulting from improper use are not subject to warranty.
