We dive deep for the ocean's finest sponges. These rock island sea sponges are grown in deeper colder waters so they are firmer and last longer. The firmness of this sponge helps when scrubbing grime. These sponges are safe to use on glass, plastic, metal, and plexiglass. They are also great to use on French panes, cutups, and other small windows. Every sponge sold is of premium quality and are now unbleached. Recent research indicates that bleached sponges will fall apart more readily than unbleached sponges.
