Mercedes-Benz wiper, model A 177 820 99 00, one piece. - Brand: Mercedes-Benz - Model number: A 177 820 99 00 - Quantity: 3 sets - Type: Wiper Thank you for viewing. I received this from an acquaintance, and I don't know much about the product itself, so I may not be able to answer questions (I can check if you give me some time). All 3 sets have damaged boxes, but they are new and unused. They became unnecessary due to a vehicle change.
