High-performance 350mm wiper rubber, effectively drains rainwater. - Model Number: 101 - Size: 350mm - Type: Wiper rubber Thank you for viewing. I purchased this at a home center to replace my wiper rubber, but I realized the width was different after opening the package, so I am selling it. The bag has been opened, but it is new and unused. *Please refrain from purchasing if you are sensitive to items that have been handled by an individual. *The black powder on the rubber surface is a component that improves the wiper's movement.
