Always respecting the environment, Tek uses for its elegant Luxury line different materials such as olive wood, "Kaleido" wood, Rhodoid and other fine African woods. Olive wood is one of the finest woods and it is used to create a very elegant and refined brush line very similar to that of Prestige brushes where precious African woods are combined with the excellent properties of TEK brushes, creating a product that satisfies all the needs. The brushes made of "Kaleido" wood are the result of the most sophisticated Italian technology applied to the wood. The surprising kaleidoscopic effect is obtained thanks to the ultrasonic assembly of colored wooden sheets. Finally Rhodoid is the most precious of all cellulose acetates, the only polymer that does not derive from petroleum but from vegetable elements such as wood pulp and cotton fiber.
