HAY’s Plant Pots add a minimalist, industrial touch to your home, garden or balcony. Made of polystone, an innovative material that combines the porous feel of concrete with plastic-like lightness, Plant Pots can be used both indoors and outdoors. If you use them as outdoor planters, it is a good idea to take them inside during winter when it’s particularly chilly. Plant Pots come with matching saucers.
