Wiper blades that are known on Minkara (a Japanese social networking site for car enthusiasts) to not chatter, such as those for the Prius 50 series (early model). A set of BOSCH Aerotwin wiper blades, AJ40TL and AJ70TL. - Brand: BOSCH - Model Name: AJ40TL - Model Name: AJ70TL - Size: 700mm, 400mm - Compatibility: All Season - Type: Aerotwin J-Fit (+) - Mounting Shape: Top Lock Type Although the package has been opened, these are new and unused wiper blades for the 50 series Prius (early model), Top Lock type. Please note that some Prius 50 series (early model) vehicles are not compatible with U-shaped wiper blades, so please check your vehicle's wipers carefully before purchasing. Reason for selling: I replaced only the wiper rubber of the original wipers, but they were chattering. I purchased these, which are known on Minkara to not chatter, and opened the package to have them installed at the dealer. However, I was advised to replace the entire wiper arm, which I did (for a fee). Therefore, these are no longer needed, and although the package has been opened, they are new and unused. I will sell them to someone who can use them. Also, I am selling the Top Lock type wiper arms (with wiper rubber, used for 3 months) that were removed for the replacement. If you purchase them together, I will offer a discount, so please consider it. If you have any questions, please feel free to ask. Please understand that the package has been opened, although the items are unused. Thank you for looking.
