Make a splash at your celebration with our Giant Foil Mermaid Balloon! Measuring 29 inches when fully inflated, this giant foil balloon will look amazing at your mermaid birthday party. Just inflate this self-sealing balloon with helium, and use curling ribbon to tie it down to a balloon weight or the guest-of-honour's chair. Or, fill it with air, and slide it onto a string with the attached tabs to create a DIY balloon banner. Take your entire party out to sea by shopping the rest of our mermaid themed party supplies.
