Basically, leather is a durable and very easy-care material. Through use, it develops a patina that protects the material quite well from soiling. Surface dirt on the leather wallet can therefore be easily wiped off with a damp cloth.
By occasionally applying leather grease, you ensure that the material remains permanently elastic and hard-wearing. To do this, take everything out of the wallet and then apply a thin layer of leather grease to the outside of the leather. Work the grease in a little and give it a few hours to soak in. Afterwards, all you need is a dry microfiber cloth to remove any excess grease. The care is complete and the leather wallet is ready for use again.
