This is a set of 4 acrylic scrubbers, categorized by type and size. They are generally used for washing dishes without detergent, but have various other uses. They're great for removing tea stains and cleaning cloudy glass, and I personally use them in the washbasin and bathroom as well. The third, rectangular one is double-woven for extra durability. Made of 100% antibacterial acrylic. - Colors: Pastel, Blue, Yellow-green, Purple - Shapes: Round, Bag-shaped, Rectangular, Mini square - Material: Acrylic - Quantity: Set of 4 Please note that these are handmade, so there may be slight variations in size. Thank you for looking.
