Please avoid getting your jewellery wet or spraying cosmetic products directly onto.The leather will withstand getting damp, but not soaked. To dry your leather jewellery, please do NOT use a hairdryer or leave it on a radiator. If your piece gets misshapen due to water, reform the piece and allow it to dry naturally. The oxidised silver used in the claps has been treated with a chemical solution to give a dark grey/black finish. This does wear away over time but is part of the character of your piece. To clean the leather, use a cotton wool bud with a tiny amount of neutral shoe polish. Should the edge dye become dirty, then please LIGHTLY wipe with a cotton wool bud dampened with water.To clean silver posts on earrings, please use a silver cleaning cloth. Do NOT put your piece in silver dip.
