This is a gray cover designed to make cleaning your drain easier. I tried it out, but it didn't fit my drain, so I'm selling it. I've trimmed it around the edge, so it's compatible with drains that have a diameter of 14.5cm or less. I'm including the remaining four nets. Photos 6-8 are for reference. I threw away the packaging, so I will send the item shown in photo 1. Thank you for looking.
