Leather is a comfortable, heavy duty material. It’s highly durable, but not indestructible. Keeping it in good shape requires constant care. Natural Leather Care, Holmenkol’s new, universal deep leather conditioner, reduces the amount of maintenance required for all types of smooth and full-grain leather in shoes, textiles or upholstery. Not only is this innovative leather conditioner gentle on leather, it’s also harmless to humans and the environment: it consists of renewable natural materials and is free of preservatives.
