This is a set of 6 eco-friendly scrubbers. These acrylic scrubbers are approximately 10cm in diameter and 5mm thick. They are handmade, so there may be slight variations in size. They have loops for hanging. They can clean dishes, tea stains, and coffee marks with just water, without the need for oil-based detergents. To care for your eco-scrubbers, if you don't mind, you can put them in a laundry net and wash them in the washing machine, then hang them to dry for long-lasting use. When they wear out, they can be used for cleaning sinks, screen doors, and window sashes.
