Đông Cứng Mặt - Thiệp Chúc Mừng Tình Bạn & Tình Yêu NSFW

I slipped this into my best friend's birthday envelope without warning and her face went completely red before she burst out laughing. The NSFW wording is genuinely shocking but there's a real sweet message underneath, which is what made it work. Printed on sturdy card stock too, no flimsy bending.

My coworker’s jaw literally dropped when she opened this, then she laughed so hard she cried—the shock value is perfect. The card manages to balance crude humor with a sweet message inside, which is exactly what I wanted for a friend who appreciates both.

Bought this for my best friend's 30th and she actually teared up laughing before she even finished reading it. The NSFW punchline lands hard, though the inside is a little cramped for writing a longer message.
