Review on Uxcell Replacement Soldering Cleaning Sponge by Kipp Amundson

As much as I would like to give this product fewer stars, at this price point you can't complain. They will work in a pinch but as you can see from other reviews they are very flimsy and warp a lot when dry. A true OEM part for my application costs about 20x more and is at least 3x thicker. If you just need something to get the job done, this is probably fine. If you make a living from a soldering iron or need high quality, go with a reputable brand.
