美國精神星形箔氣球

Hung this up for my son's birthday and it stayed fully inflated for three days without needing a top-up. The foil is thick enough that it didn't wrinkle or droop like the cheaper ones I've bought before.

The cluster shape really filled out the corner of the room where we hung it, and the foil held its shine the whole afternoon. It survived being bumped by the kids and stayed fully inflated until we took it down the next day.

The foil is thick and doesn't crease easily during inflation, which surprised me for the price. It held its shape perfectly through the whole party and even stayed inflated the next morning for photos.
