The gently rounded shape of the Swisspearl Sumo Pot makes it immediately appealing. Through its rounded form contact with the ground is reduced and the top of the planter rolls in to embrace the plants within. Because it is made from lightweight cement the planter it is easy to handle despite its large size. Based in Switzerland, Swisspearl is a company who has been specialising in cement products since 1903. Their products are made from a blend of cement, powdered limestone, cellulose and synthetic fibres, water and air. The result is the look of real poured concrete but at a fraction of the weight.
