She's your sister, your lifelong partner-in-crime, and yes – your favourite (but don’t tell the others). This cheeky birthday card says what you kind of mean, in gloriously passive-aggressive fashion. With bold black typography and a dramatic yellow highlight on FAVOURITE (because drama runs in the family), this A6-sized gem delivers laughs and sibling superiority all in one go.
Printed on gloriously thick, high-quality card that feels posher than your sister’s Prosecco addiction, this card is blank inside for your own sentimental waffle or petty in-joke. And that little line at the bottom? “(Don’t let it go to your head)” – because balance is everything.
Perfect for sisters who love a laugh, know their worth, and enjoy being very smug about it.
Why you'll love it:
-
Witty, sarcastic and guaranteed to cause sibling side-eye
-
Printed on luxe, textured cardstock – none of that flimsy nonsense
-
A6 size, ideal for posting, framing, or dramatically waving about during family Zoom calls
