The Volumes pots by Serax play with different thicknesses and heights of seemingly simple shapes. Designed by Dutch Piet Boon, the collection’s subtle color palette was inspired by the paintings of Italian artist Giorgio Morandi. The Volumes pots are made of stoneware and available in a variety of sizes. As there is no drainage hole in the bottom, plants should not be planted directly in the pots – you can place a plastic pot and saucer inside them or use a plastic bag.
