I purchased 6 packs of these in assorted colors for a birthday prank on my wife. I inflated them with a small shop blower and filled our den/living room. They inflate very large, maybe too large because some randomly exploded during inflation and when they hit the hardwood floors. Needless to say, she was very surprised when she walked in and by the random pops all weekend. They do what balloons do and I would buy again if the need arises.We got these for my sons birthday and they’re literally still inflated. I don’t have a problem with the scent but I also don’t go around sniffing balloons…One thing to note is they’re very large! Unfortunately his birthday was on a holiday and party city wouldn’t blow it up without an order so I took them to a Tom Thumb and because of the size they charged me $15 A BALLOON. Moral of the story is get your own helium, blow them up yourself, or plan ahead!The quality of ballon was just okay. The price equals the quality. They did however work out well for the event. The balloons in the photos are sprayed with a balloon shine product. If your in a time crunch and need something quickly these may work for your event.big bright & very nice quality balloons in bright green color. No issuesThe quality is not that good a few of thembroke while I was handling itThese were not forest green but more of an emerald green. They didn’t match the rest of the balloons for my event.The dusty/chalky coating on these was HORRIBLE! The balloons were think and did inflate easily but we had to wipe/dust down each individual balloon for the party. I wouldn't repurchase but they did do the job.These balloons are like latex gloves. They easily stretch and expand, but are not very durable. I would not recommend inflating them with helium or exposing them to the outdoors if you intend on seeing them last more than a couple hours.
