Fun Express Science Party Mylar Balloons | 3-Pack | Great for Party Decorations, Holiday Celebrations, and Science-Themed Occasions

I read other reviews that they had holes in them so I was a little worried but these worked great! Perfect addition to my sons science themed bday party! Once filled with helium they lasted 2 weeks!

Exactly as pictured. Great quality balloon. Came on time and held up very well. Made a wonderful centerpiece for my science party.

These ballons were a hit. The color is vibrant, and they were actually a bit bigger than expected.

Cute for a science party! As expected

These were so cute but horrible quality! We inflated them with helium and within an hour all three had leaked and would no longer float! Such a waste of money.

Exactly as pictured, perfect balloons for a science nerd!

Two of the three balloons had holes in them and I was unable to fill them with helium at the party store.
