This decoration set by #iLoveCos has a nice selection of different balloons including foil ones and confetti ones as well as the happy birthday banner. A balloon pump is included as well as balloon ribbon and straws for the balloons instead of using ribbon. There are also tassel decorations which can be used as a garland.
Helium or just air can be used. If you rub the confetti balloons on your hair or on the carpet to create static, the confetti pieces inside will stick to the sides of the balloons. The balloons are nice and strong, especially the foil ones.
The only disappointing thing is that the balloon pump doesn’t have enough oomph to actually pump up the balloons! It’s really too small and even if you wrap your fingers around the end of it to stop any air leaks it doesn’t pump up the balloons at all.
This is a great birthday set though and will really look nice, the rose gold colour is awesome!
