These are super cool but definitely require practice. And they absolutely HAVE to be stretched significantly before inflating, otherwise it won't work... like I almost thought I was gonna tear them, that's how much you have to stretch them. It was almost a work out just doing the stretching part lol. But once you get the hang of it, the results are awesome in person. They don't photograph super well but, trust me, in person, they add visual interest/dimension that put your balloon decor on another level.We followed the instructions but couldn’t get the wrinkles out of the sides. We tried many different techniques but they just aren’t able to get perfectly rounded. You also had to tie them VERY tight or they would deflate overnight. They served their purpose as underwater bubbles for VBS.These are great balloons once you learn how to use them. You really have experiment with these balloons and because they're not expensive you can do that. They do initially inflate like a pill but if you kinda squeeze it before tying it you can reposition the air.Everything was perfect all pieces were in there. Easy to inflateThey don’t float, they are too heavy with the lights on. We even tried high float in them. They aren’t reusable either. That said I used them at my sons wedding. Absolutely stunning backdrop. We made a stand and hung them from different lengths. The entire glass wall looked like the night sky.I do some balloon work and they were perfect for printing names on vinyl and decorating the balloonI got these because i came across the same balloons which was way more expensive then i decided to make my own. I have to say they’re not the best quality but theyre not the worst either. Can work with it. Just dont inflate and deflate it more than twice or they will popBalloons are good would definitely buy again, I have only blown up 2 of the biggest size to test run before I work with them officially. Must say the first one I blew up about 4 days ago is still going strong. The one in the pic is freshly blown and I have no complaints! They do require some arm strength as the do need some good stretching before they will blow up to full size. If you skip this step be warned they will just POP! Deffo did get a slight cramp lol.The first lot of these I brought was perfect so I ordered the same one from the same place but to say I'm disappointed would be an understatement!!! Keep popping and can't get past 9 inch on all of the sizes! I own a baloon business so i know how to stretch and blow them up. I thought I would order another lot thinking maybe I just got sent a faulty bunch but nope the same again and even the packaging is different so you have changed something when making them!!!!! Won't be buying them again!!!!Misshapen when inflated and they don’t stay inflated either using air or helium wasted my money. I had stretched them first to make inflation easier a few burst while being inflated too. within 24 hours of inflation the balloon is now very small went from a 16 inch to a 7 inch balloon.These are ok but takes time to get use to it. I found it difficult to work with at first and a few popped
