There are 7 sizes in this gorgeous modern pot. They are made from Slip-cast Concrete reinforced with FibreGlass, ie GRC. This makes them strong, but very light. Great for being able to move them, and placing them on balconies and decks where weight is a consideration. They are painted, and this will fade over time, but they can be re-painted with any house paint that you can paint on a render. These pots can also form minor cracks over time. This is less likely if you seal them, and fill to the top with potting soil.
