Ella Celebration XOXO Balloons Huge 40 Inch Letters Wedding or Engagement Party Decorations (Silver) MAKE YOUR PHOTOS STAND OUT: Whether you use these as props in your wedding-party photos, bride and groom shots, as part of your engagement shoot or even in the photo booth, these will add extra excitement and shine to memorable photographs. PUT YOUR LOVE ON DISPLAY: Great for anniversary parties, weddings, showers and other special occasions. Their large size helps fill big spaces and add a romantic feel. QUICK TO INFLATE YOURSELF OR PROFESSIONALLY: All it takes is a regular drinking straw and you can inflate these yourself! Alternately, you can have them professionally inflated with helium easily and quickly if you need them to float. WON'T DEFLATE MID-PARTY: Thanks to a self-sealing valve, these won't leak air all night long while you celebrate. TIP FROM OUR HAPPY CUSTOMERS: Make sure the letter O is inflated 100%. In order to for the design to work aesthetically, the letter is not fully enclosed, and almost appears to be a C when not completely filled. Please see pictures for reference.
