You’re going to make some 7 year old super happy with this 18 inch Happy 7th Birthday balloon! Adorned with colourful birthday candles and stars, this balloon is sure to be a hit on your child’s special day. Just needs to be filled with helium. For extra “cool parent” points let your kid suck the helium out of the balloon the day after so they can sound like Mickey Mouse. Or don’t. We’re not sure if you should try that at home.
