Interstyles newest line Spark incorporates 3 different textures in 6 color ways. Spark is more than just a new series, it is a new finish as well. It is fired face-up and face-down, with a dune and sandstone texture which results in a new unique texture. Each blend name was chosen for their similarities from beaches from around the world. The colors are inspired by how the water and light interacts with the precious stones and sand below.
