These are PIAA flat snow wiper blades. The size is 600mm. They arrived yesterday (R7/10/8) and are new, never used. They didn't fit my car, and I couldn't return them, so I'm selling them. Here's a more detailed explanation: I bought different clips, thinking I could swap them to fit my car. However, the separately sold clips didn't fit this blade. While trying to remove the clip, I damaged it and replaced it with one from another blade. Therefore, I'm selling it as a used item. Everything except the clip is definitely new, so I hope someone who can trust this will purchase it.
