Large Number Silver Foil Mylar Balloon

The silver foil is way shinier in person than the listing photos suggest, and it held air for the entire week before the party. Stood up fine on its own without sagging, which I wasn't expecting from a mylar balloon.

Inflated this in about ten minutes with a hand pump and it held air perfectly for the whole weekend. The oversized numeral made a big statement above the dessert table without any helium. My son was thrilled to keep it in his room after the party.

Bought this for my daughter's 10th birthday and it held air for almost two weeks after the party. The silver mylar is really shiny in person, caught the light nicely in all our photos. Would grab another one for her next milestone.
