I had read some reviews that the balloons were thin, popped easily, or leaked air. I received these on 6/27 and set them up on 6/28. They were perfect! The balloons were very sturdy; none of them popped upon blowing them up and only one has popped since yesterday (they’re on the floor so I chalked it up to a fair reason why it popped - it was also a confetti balloon and now there’s cute gold confetti all around! Easy to vacuum, but it’s cute so I’ll keep it while our decor is still up). Not all balloons are shown in the photo as I did not blow them all up (there’s so many!). The banner was made very well and I’ll be able to reuse many times. The number & star balloons came with matching straws that allowed me to EASILY blow them up by mouth. The one negative thing I found about this purchase was that the paper puffballs included weren’t the easiest to make. I made the first one (white) following the directions shown in the product photos, but it made an ugly ball. I ended up making the second one (black) by pulling apart all of the paper BEFORE tying the string in the center and then grouping them back together and tying the string. I then was more easily able to make a prettier puffball. They were time consuming to make, so I didn’t make more than that. Ended up using the rest as tissue paper for gifts since they were made of that. Despite the puffballs, I 100% recommend this bundle!Note: I was NOT paid or given any incentive to write this review; just happened to have a decent pic and figured I’d help the community. Hope you all have the same satisfaction as I did!
