The Laguna Series are hand-thrown and altered porcelain forms, each piece uniquely shaped to create a sense of movement and fluidity. Each is embedded with a "keyhole" for simple installation. I supply the screws. I recommend an anchor but as these are light weight, I don't always use one as it depends on the hardness of each wall surface. 
Sizes range from 6 to 11" in diameter and rise off the wall approximately 3". The image shown with the grouping is a bit "flat" as the app I use to group them doesn't show the depth of the pieces. The individual images show the more realistic depth of each of these pieces.
