White balloons in Tokyo: how long they float and what they come with
White balloons in Tokyo hold their helium for about half a day when the latex is left untreated, because latex is porous and the gas seeps out through it. A polymer coating called Hi-Float can stretch that float time to several days, and a foil balloon holds its helium for several days on its own. The latex balloon in this grid is timed for the day it arrives, so it is worth planning the balloon around the handover rather than the week ahead.
White with gold, black or pink
None of the balloons here comes in white alone. The cloud pairs white with gold, the fountain pairs white with pink, and the balloon printed with Happy Birthday! runs through gold, black and white together. Choosing between them is really a choice of scale: a single balloon suits a small gesture, a cloud fills more space, and a fountain reads as the centrepiece of a table.
Balloons go into the basket alongside a bouquet or a box of sweets, and the card that travels with them costs nothing extra. It can carry a signed message or stay blank, so the balloon can arrive from someone the recipient has to guess. Most orders placed this way are handed over on the same day they are ordered.
A balloon rarely travels alone, and pairing it with flowers or sweets is worth planning before checkout: gifts to go with bouquets lines up the combinations that work with a balloon cloud or fountain. For a simple pairing, a bunch of roses sits well next to any of the three formats above, and how delivery works explains how the order reaches the recipient on the day.
