The photo may be slightly different from the actual item in terms of colour due to the lighting during photo shooting or differences in monitor and screen display.


  • Balloons are sent UNINFLATED in sealed packaging and must be INFLATED to the advertised size.
  • Over-inflating the balloon will distort its shape and cause it to pop.
  • CHOKING HAZARDS: Children under 8 years can choke or suffocate on uninflated or broken balloons. Adult supervision is required at all times. Keep uninflated balloons out of reach from children and discard broken balloons at once.


Fill our 16-inch letter and number foil balloon range with air as they will not float with helium. Inflate gently, avoiding overfilling (80%-90% is sufficient).

Note: The non-inflated "O" and "B" letters may resemble "C" or "G" due to production design limitations.
