Surprise boxes in Hong Kong: gender reveal, proposal or a plain surprise
Surprise boxes in Hong Kong start with the occasion, not the colour. Most box names already say why they're opened, from a gender reveal to a proposal, while one box carries a number instead of a reason. Once the occasion is decided, the only thing left is when and where the box arrives.
Gender reveal, proposal or no occasion: picking the box
The name does the choosing: it can announce a baby's gender, invite a proposal, or simply skip the reason and rely on a number. What sits inside beyond the title isn't listed, so the name is the only guide when ordering.
The section sits in the catalogue under helium balloons, though the names don't say what the balloons are made of. Untreated latex holds helium about half a day, foil several days; ask the manager in chat which material a box uses and describe the occasion for photo options and prices before payment.
A photo of the finished box arrives before the courier leaves, so changes are still possible then. The card is free and can stay unsigned. Add a gift for a plain surprise or roses for a proposal box, and check delivery for zones, timing and restaurant arrangements.
