The Souverän Tortoiseshell-White radiates a warm purity with the combination of golden elements, white parts and greenish-yellow elements. This series offers an unusual color combination. The various color pigments in the material create a multicolor effect that shimmers in a wide variety of color nuances. The material, originally made of cotton, got its name from these color effects. The white precious resin offers a successful color counterpart to the color swirls.
