The 320 Grit Sandpaper by POLIWELL seems to be a reliable option for various sanding needs. Customers have praised its durability and flexibility, making it suitable for both dry and wet sanding. The sandpaper is said to provide a slight grip when wet, ensuring better control during the sanding process. It is worth noting that some customers have compared this sandpaper to the 3M brand, with mixed results. While one customer commented that it is between 320 and 600 grit, another customer found it to be coarser and more similar to 120 grit. However, this can be more of a personal preference, as some individuals may prefer a coarser abrasive for their specific projects. In terms of compatibility, customers have confirmed that the 9x11-inch size is a standard size for sandpaper and should fit most palm sanders. They have also mentioned that the sandpaper tears easily along a folded crease, making it convenient for smaller sanding tasks. Overall, the POLIWELL 320 Grit Sandpaper has received positive feedback from customers. Its durability, flexibility, and reasonable price make it a great option for sanding wood, metal, drywall, resin, and automotive surfaces.
