Rear seat floor mats for Audi TT 8J model Black and red checkered pattern, non-slip. - Color: Black and Red Checkered Pattern - Material: Textured Fabric - Back Material: Rubberized Non-slip Surface - Type: Front Floor Mats I tried to clean the white areas on the back with a toothbrush, and it became a little whiter. However, it's an area that won't be visible once the mats are in place, so I'd like to offer them to someone who doesn't mind. Dimensions: Length: Longest part: 50 cm Shortest part: 38 cm Width: 28 cm Thank you for looking.
