"Wish I would have realized how time consuming these were going to be before the day of the party. Each blower is individually wrapped in plastic that you have to remove before you punch out holes on the olivia rounds to assemble them yourself. Unless you have time to improvise with glue or tape, the Olivia picture (which is why we bought them in the first place) will slide around and fall off. On a positive note: The blowers make a nice honking sound which the kids loved (parents, not so much LOL)."
