I have recently bought rear wiper blades for i30 - i20 - Mini One from ebay here
Rear Wiper Blade Fits Hyundai i30 (2007-2013) Hatchback Genuine Rocwood | eBayThey are very good match to the original blades but one advantage is that the squeegee rubber and metal strips can be removed and fitted to the original Hyundai wiper blade frame. Easiest way is to pop a swinging arm off the original Hyundai frame and slide the old rubber out then fit the new rubber into the Hyundai frame and pop the swinging arm back into the main part.
