Review on TONIFUL Black Happy Birthday Balloons Banner – 16 Inch Mylar Foil Letters | Reusable Eco-friendly Material | Girls, Boys, Kids, Adults Birthday Decorations & Halloween Party Supplies by Jasmine Davis

This very cute banner is exactly like the picture. Bought for my son's birthday a month later (mid September). It's birthday month at our house, although we're all a few weeks apart. I blew it all up and hung it up a month early and figured if it couldn't be blown up again I'd just buy another one. We've been hanging for a week now, but he's not blown away! Due to the way it was packaged, some balloons were initially more difficult to insert the straw and inflate (both sides were taped together), but they all inflated with some effort. A few letters lost some air the day after we inflated them (see A in the photos, my thumb squeezes them tight) but have not lost air since (see photo I, there is almost no indentation from the finger) . . It wouldn't be a problem if you blast it on the day of the party!
