I recommend. I’m sensitive to smells and they do smell like gasoline at first. But I had them in bags in the garage overnight (filled the garage with the smell initially!), and I put them out in the living room after kiddo went to bed. By the time I put them out or morning, I can’t remember which, the smell was gone. They do make my hands feel kind of icky after handling.For the confetti ones I did add 2 drops of water to each. And some confetti stuck to the balloon because of it, but it was easy to push them off and unstick them.They’re super cute. Totally worth it for a thematic party.
