Thank you for viewing! Reusable! Washing Machine Drain Cover Silicone, White, Set of 2, Igatta Size: Outer diameter 16 cm, Inner diameter 3.5 cm, Thickness 1.5 mm I tried using it at home, but the size didn't fit... I'm selling it without ever using it. The packaging was opened in a strange way, as shown in the photo. Although unused, it has been opened once, so please consider that there may be some fine dust, and please check the photos before purchasing. Just in case, I will wipe the product clean before shipping.
