We often receive inquiries about wiper blades. It's usually requesting wiper blade assembly that includes bracket of the blade rubber. We wonder if the customer really needs assembled one whenever we received such inquiries. Maybe he doesn't know blade rubber is available individually. Or, he doesn't know how to replace the rubber.
Replacement of the rubber is very easy!
The rubber includes thinner metal reinforcement covered by the rubber, and whole rubber is mostly fixed by a small projection of the rubber itself. If you pulled the rubber a little stronger, the rubber can be removed easily. No special tool like a plier is required.
Also, price is much cheaper than assembled one. In addition, depending on the vehicle he owns, water repellent finished-rubber is available.
