This won't help the OP but for folks in North America, Rockauto is a great source for these.
Rear: BOSCH Part # 3397004559 - $11
Front set: BOSCH Part # 3397118423 - $17.50 for the pair
Both are OEM style parts - driver's side wiper has the spoiler feature, rear is partially enclosed.. just like the originals.
While you're there, order an activated carbon cabin filter ($17, DENSO Part # 4542005) & air filter ($10, MAHLE Part # LX343) too.
