Please read the profile. It's easy to set up, catches fine debris, and is resistant to clogging. Made with double-russell mesh, it's tear-resistant and has excellent water drainage. It stretches horizontally but not vertically, allowing you to adjust it to various sizes. Because it doesn't stretch vertically, you can easily remove the net even when it's heavy with debris, and the debris is less likely to bounce back when you take it out. Just take it out and throw it away! It's hassle-free, so it's always clean. - Material: Polyester - Dimensions: Approximately 35cm (length) x 30cm (width) - Quantity: 10 sheets x 6 sets - Condition: Unused, packaged Ideally, we'd like you to purchase all 6 sets, but one set is also acceptable.
