Each 'Tiane Tenui bag is a true representation of the philosophy of the brand — made from leather that hasn’t been coated with synthetic top finishes or unnecessary industrial protection so that the true nature of the piece will always be visible. The surface of the bag will change over time with exposure to being carried in hand or everyday elements. Christiane recommends avoiding rain or prolonged direct sunlight and suggests that her customers polish their bags with leather creme or protect them with a spray to avoid water spots or sun damage.

Longevity is a result of the passion for making a quality product that inherently lasts a lifetime. Since Christiane has put in an enormous amount of time and effort, the leather often tells a story through its patina, created over time. It becomes more beautiful, the color might change but the customer ultimately builds a relationship with the bag; it becomes a part of their lives.
