Make your celebration shine with our foil gold "M" letter balloon! This foil balloon measures 14 inches when fully inflated, so it's a great size for adding to a DIY letter balloon banner. Just inflate this letter m balloon with air using a straw, and combine it on a string with more of our gold letter balloons. After spelling out your special message or name, hang this banner on any wall at your birthday party. Find more ways to celebrate in style and shop the rest of our gold party decorations.
