Natural leather is highly sensitive and should be treated regularly with leather grease, balm, or special care creams to maintain its suppleness and prevent it from drying out. Before first use, it is recommended to apply a waterproofing spray to protect the porous material from moisture and stains. Because the leather is untreated, it offers a wide range of design possibilities: Over time, it develops a unique patina, but it can also be darkened or colored to suit individual preferences by applying colored oils, waxes, or stains.
