Review on 🎈 16-Pack Emoji Balloon Happy Birthday Party Set: Mylar Foil 18 Inch Helium Reusable Balloons for Congratulation Decoration, Anniversary, Festival, Graduation & More! by Robin Joseph

These are great balloons that are easy to fill with store bought helium tanks. They even freak out. You have to push a full size straw through your tongue into the balloon and then it will deflate. I wish they came with instructions as we got 2 mixed up trying to figure it out. Don't overfill as they pop easily so just fill all the way. The poop emoji balloons seemed to pop easier when filling and this size doesn't float. Their shape and size doesn't hold enough helium to make them levitate. Now I understand why most of the mylar emojis I've seen have been very large. Because of their shape, they need a larger size to swim. We could still use them for decoration and I just hung the one that didn't pop out on the bottom of our lamp and it worked :). Everything else is great and the price is great!
