Pascale Lion is an interior architect and designer based in Paris. She teaches at the Paris’s National School of Decorative Arts. In addition to her professional work, she also teaches at the National School of Decorative Arts in Paris. Over the course of the past two decades, Pascale has devoted much of her time to exploring metallic meshes, after first developing items for large-scale industrial use.

Pascal Lion views jewellery as a continuation of this research, exploring simple shapes and simple uses to bring chainmail into everyday life. Since she created her first necklaces back in 2009, her minimalist designs and timeless materials have attracted a loyal following. The pieces are made to last many lifetimes, and are also incredibly comfortable to wear. Today, Pascale's OOOO collection includes over a hundred different items, which can be found in quality concept stores and museum shops on all five continents.
