Pia Super Water Repellent Super Strong Silicone Coat Replacement Rubber 600mm and 450mm I opened the package but realized I ordered the wrong size, so it's unused. Replacement rubber for car windshield wipers. Metal rails are not included. Packaging and Shipping: As shown in the photo, I will put the rubber in a bag, slightly roll it up, wrap it in bubble wrap, and then put it in a Mercari-branded colored vinyl bag. I will ship it via Yu-Packet Post.
