£12.33 for a set for my Mazda which isn't bad apart from the driver's side being an inch shorter than original. It's not a problem for me but my wife says she would miss the extra inch.
Mk7 fiesta, 2009 onwards, have aero style blades. These are a traditional style so may not fit.
Be careful though, I had an issue with interior bulbs - they said it will fit and it didn't - had to speak customer services to get return charge given back.
Shame this doesn't my Toyota Corolla Hatchback 1.8 ... Seems good price so voted hot
I think Mk 7's are 26"/16", so not compatible. I think these will do you, but check before buying. https://www.amazon.co.uk/dp/B002QQZU10?_encoding=UTF8&isInIframe=0&n=248877031&ref_=dp_proddesc_0&s=automotive&showDetailProductDesc=1#product-description_feature_div and https://www.amazon.co.uk/Bosch-SP16-Super-Universal-Single/dp/B002QQTPSY/ref=pd_bxgy_263_img_2?_encoding=UTF8&psc=1&refRID=Q9QHFEQ7ZGXSF5R73RGH
