The sisters' card is made of FSC®-certified paper and measures 10.5 x 22.8 cm. It comes with a matching envelope.

"Happy birthday and many happy returns," Anna finishes the greeting card and slides it into an envelope. "It is always nice to receive handwritten messages on one's special day, is it not?" she asks with a smile. "Absolutely! Those always feel like they come from the heart, dear sister," Clara agrees.
