Review on 🧽 Efficient Disposable Non-Scratch Dish Sponge Scrub Scouring Sheets for Versatile Cleaning: Kitchen, Dishwashing, Camping - Heavy Duty Blue Pads - 1 Roll Lasting 60 Days by William Dean

They come in rolls of 60 8.66" x 8.66" blue polypropylene sheets, plus or minus 0.4 feet thick. The Republic of Korea is given as the country of origin. They come off the roll easily. The material itself doesn't absorb water, but it "wet" and wore out, and also washed off easily. I used one to clean the stainless steel sink myself and found the cleaning power to be a little above average despite being very thin. For those interested in biodegradability and recycling, there may be concerns about the "disposable" aspect, although you can probably glean multiple uses from it as well.
