I purchased this item, but the drain size didn't fit, so I'm selling it. I opened the package, but it's unused and has never been in contact with water. This is a used item, so please refrain from purchasing if you are looking for a perfect product. [Product Description] The ultimate hair catcher that frees you from the stress of cleaning is here! It's designed to prevent clogging and is rust-resistant. It can also be easily removed with a magnet. [Important Notes] Please confirm that your drain opening is between 36mm and 45mm in diameter. This product cannot be used if the drain opening is less than 36mm. If the drain opening is too wide, this product may shift. Also, if there is a cross-shaped strainer about 3cm below the drain opening, the space for collecting debris in the net will be significantly reduced, which may greatly impair the drainage performance of this product. Furthermore, please be aware that if debris accumulates beyond the cross-shaped strainer, the drain net may become difficult to remove.
