What is Scratch and Dent?

Scratch and dent items are products that have minor cosmetic imperfections, such as scratches, dents, or other surface damage, but are otherwise fully functional. These items are typically sold at a discounted price due to their less-than-perfect appearance, making them a great option for those looking to save money on products that still work as intended.

All sales are final - no returns are accepted on Scratch and Dent items
