This is a custom-fit, all-weather cargo or trunk mat for a Lexus RX vehicle.
The mat is typically made from durable materials like TPE (thermoplastic elastomer) and is designed to protect the vehicle's cargo area from dirt, spills, and other damage. These mats often have a raised lip and a ribbed or channeled surface to contain liquids and prevent cargo from shifting. They are also lightweight, waterproof, and easy to clean.
