Includes mini straw for easy air-filled inflation. This balloon is designed to be inflated with air only and does not float with helium. Spell out the name of your choice in style with Betallic's new Script Letters! These air-filled balloons feature strategically placed hang tabs on each balloon allowing you to thread ribbon or string through each letter so they hang evenly and in line with the next letter. Note: 35cm and 60cm letters are designed to work with each other and are in fact in the same balloon line. Dimensions are based off the size of the letter. Example, using a 35cm "a" and 60cm "t" would spell "at" and would look in proportion to the next letter. Ribbon/string not included. Inflate balloons with air-only. Balloon does not float and arrives uninflated.
