The Faux Artist Sea Sponge is used by professionals and artisans for wallpapering, texturing, creating faux painting effects, pottery-making, and other types of projects. Please note that these are not whole sponges intended for decorative purposes. Native to the coastal waters of Florida, natural sponges have been used for hundreds of purposes for over 2,000 years. Natural sea sponges, unlike artificial sponges, are 100% biodegradable, naturally inhibit the growth of bacteria, are environmentally safe, economical, sustainably harvested, and a quickly renewable natural resource. As with any natural product color, size and shape will vary.
