Review on 🧽 Dr.WOW 21 Pcs/Lot Magic Sponge: 2X Thicken 2X Long Lasting Cleaning, Eraser Sponge for Kitchen, Bathroom, Office - Great Price Melamine Sponge for Air Fryers & More by Joy Berry

These erasers are made from the same material as the popular branded Magic Eraser. They even weigh 15 g each, but are about 1.5 times thicker. Because they aren't as dense, there are fewer abrasive areas in contact with the surfaces being cleaned. You can still get the same results, but it takes more effort and isn't as "magical" as more expensive, denser products. Still good value for money, just be prepared that they work closer to a standard eraser than a Magic Eraser.
