Mercedes-Benz Wiper Blade A 176 820 27 00 Genuine Mercedes-Benz wiper blades. I purchased these a few years ago and stored them, but I'm selling my car and won't be using them, so I'm putting them up for sale. I opened the package to check for rubber degradation, but there didn't seem to be any obvious deterioration. Please refer to the photos to make your purchase decision. I will ship the item by wrapping the original box directly with bubble wrap. I was planning to use these on a GLA.
