'Onyx' Round Pottery FormIrregular round pottery form drape mould with soft roundover edge. Available in just one size (large) and designed so you can nest the smaller sizes in our Nature collection within this size. The Nature collection is inspired by the beautifully asymmetrical, organic shapes found in nature from river stones and pebbles, to moon phases and natural rock arches. Don't forget to add on the screw in Base Handle which can be purchased separately here. Fin
