It's very thick, the light is very bright. I would say the quality is very good. My roommate and I like it so much because the balloons are so pretty, especially at night. The only thing is we can't use mouth to blow up the balloons, we have to borrow a tool from my friend. Other than that, everything it's perfect.
I like the appearance of these balloons, and I like LED as well. I use hand-held balloon pumps, which are easy to inflate, and when inflated, reach 18 feet or more. They look environmentally friendly and have no odor. It brought me great happiness to my birthday party yesterday, and I will buy it again next year!
LED lights not only can use in the ballon. It can also use in many different ways. I use in my kids dress. The dress looks perfect at night.
Super cool! Inflating was kind of tricky, but once I got the hang of it, it got easier. These are reusable, which is awesome. The balloons with the lights also look SO COOL!
