These were large awesome balloons for my nephews bday party.I did a unit with the students on the James Webb Space Telescope. Perfect decoration. Only issue is that I didn’t realize stores who sell balloons won’t inflate balloons bought elsewhere at any cost. I finally got a local food store to do it for a discounted price of $9 each because they were so large.Excelente inversiónAbsolutely hands down beautiful balloons as a matter of fact they are so nice we kept them and still have them still full of air months later??Adorable balloons, big, just difficult to get on the top of the helium tank. 2 leaked, one tore.Loved these balloons!! Great quality and stayed inflated for so long!The kids loved these! They were very durable. 4 weeks later and still inflated and entertaining everyone. Even the dog!These were perfect for my balloon garland.
