Ideal for quickly covering larger areas, blending and stippling effects plus many other decorative art techniques. These excellent quality, natural sea sponges harvested in the Aegean Sea, near the Island of Kalymnos in Greece, are ideal for sponge painting, staining, stippling and faux finishes. Can be used with acrylic, oil, watercolour and fabric paints. To maintain their good health, it is necessary to rinse them in cold, clean water after use and squeeze out gently any excess water and leave to air dry.
