These planters were designed by Willy Guhl, a famous Swiss designer and then edited by Eternit in 1950. These planters are made of Eternit, a stable material with a fibrous texture composed of cement. It consists of a molded Eternit slab in the shape of a handkerchief. This material, innovative for the fifties, can take all the desired aspects as long as it's not dry. Due to its high strength, it's totally adaptable to outdoor furniture.
