The slender hanging lamp of Foscarini Titeuses a fiber glass fabric
diffuser. It comes in three sizes and uses two colors. On the one hand
there is the yellow Kevlar thread, on the other hand there is the
black carbon thread. They form good effects and provide quality
lighting to fill rooms with soft diffused light.
