The outer box has scratches and dents, so I've listed it as "Like New," but the contents are fine. [Set Contents] 150mm (6 inch) PSA Sanding Discs #80 50 sheets [Material] Made of high-quality aluminum oxide, offering higher cutting efficiency and abrasion resistance than silicon carbide. Provides a fast and sharp cutting edge that lasts a long time. Resistant to clogging and loading, leading to improved productivity and reduced material consumption. [Design] The sandpaper discs have an easy pull-off tab for removing the backing paper, protecting the PSA pressure-sensitive adhesive of the sandpaper disc from dirt. [Features] The strong adhesive backing is designed to quickly and securely adhere to the PSA base plate of DA sanders. The enhanced adhesion with the sandpaper disc ensures that the disc remains firmly attached and stable even during high-speed, high-load operations, allowing for more efficient and continuous sanding and polishing work. [Applications] Ideal for any surface requiring precision sanding, such as automotive repair and paint shops, woodworking and wooden furniture making, metalworking, crafts, household chores, drywall projects, industrial applications, fiberglass processing, and plastics. 2-89
