大型黑色鋁箔數字氣球

Held air for a full week before the party and still looked crisp on the wall. The black foil has a nice mirror finish that photographs way better than I expected for the price.

This balloon held up way better than I expected for a foil mylar one, and it didn't deflate at all overnight. The black is actually matte-ish and deep, so it looked really sharp against the pastel backdrop at my daughter's 30th.

The black foil looks really sleek against a bright backdrop, and the number is huge enough to be seen from across the room. It inflated easily with a straw and stayed firm the whole party, though I wish it came with a hanging string included.
