Celebrate your sister — and your odds of surviving the apocalypse — with this funny birthday card for sister featuring the epic line: “Happy Birthday to My Sister I Trust to Not Kill Me During a Zombie Apocalypse.” Equal parts hilarious and heartfelt, this card is perfect for the sister who always has your back… and your bug-out bag.
Whether she’s your older, younger, or twin partner-in-chaos, this card delivers laughs with a twist of end-of-the-world sibling loyalty. It’s ideal for sisters who love dark humor, binge zombie shows, or just appreciate a good survival joke.
Printed on thick 324gsm cardstock, the card has a smooth matte finish and a blank interior — perfect for your custom message of love, sarcasm, or your plan for where to meet if the world ends.
Give her a birthday moment that’s as unforgettable (and slightly unhinged) as your bond.

My sister absolutely hates zombies and all that scary stuff, so I just had to get this to her. She hated it but everyone else liked it!
