These balloons are extremely pretty! My favorites of the 8 or so types I bought to make balloon garlands and such for a recent baby shower. They were pretty difficult to blow up, hard to tie, and they were also more likely to pop in the sun than the other balloons because they are doubled with a dark charcoal grey balloon underneath. That balloon absorbs a bunch of heat and pops the out balloon that creates the green effect. All of the inside balloons held up great but all of the outside outer balloons popped. But they are very pretty and a very good value for the quality of these balloons.I don’t know if it says this in the description but these balloons have a purple balloon inside them and are very hard to inflate.I used this to make a balloon arch for my graduation party from UT Austin and the color is great. The only tricky thing is that the inner balloon is extremely fragile and was very difficult to blow up the balloon without it popping making the color not burnt orange and on the opaque side. If you plan to use all 50 I would buy an additional pack to anticipate the inevitable popping of the inner balloon. Was a bit tedious. Once successfully tied off work with care because that inner balloon pops with just a little bit of jostleThese are some of the prettiest balloons I have seen in my life, but they are double layered and impossible to blow up by normal techniques. I was using an electric inflator and still had to take each balloon apart, pre-inflate each layer individually, and then re-insert the interior balloon to make it possible to blow them up together. That means you are going to spend at least 3 times the normal amount of time to inflate these. I would absolutely purchase them again as accent pieces, but it would be nearly impossible to use these for large columns or arches where they are the main filler.This is my first time using double stuffed balloons and I still don’t get how regular clear green and metallic purple make this rich/dark teal/emerald color but it is BEAUTIFUL!! It was the exact color I needed. I inflated with a pump and tied off only the inside balloon as this was easier than tying both. The balloons are not sheer at all.One thing I disliked was the ability to "tie" them. As they are double-layered, they were a bit harder to tie in closing. The outer layer also burst if they rubbed together (ie for a hoop). But if using with arch "tape", should work perfectly. I loved the color so much, I was willing to look past the trouble of tying them.The double layer made it hard to inflate
