Designed to perfume small spaces like closets or car interiors, the latest innovation at fragrance house Frederic Malle is Rubber Incense ($110). According to the company, it releases perfume for a long time without using electricity or a refill. Malle designed these plastic slabs, made of recyclable ethylene vinyl acetate (EVA), after discovering IFF’s patented Polyiff process, which enables a scent to permeate plastic materials. The first batch is scented with “Saint des Saints,” a reproduction of the smell of Indian temples. Other scents include Marius & Jeanette, Rosa Rugosa and Jurassic Flower and Russian Nights, out now as candles at Barney’s and online.
