11" 19-A-Round Assortment Pearl Black and Silver (50pcs) Balloons. The number "19" is in a bold strong font of various sizes, surrounded by streamers and confetti in white ink. These latex balloons are ideal for 19th birthdays, 19 year anniversaries, or other 19 year milestones. They will work well with other latex and foil balloons with a confetti and streamer iconography. Easy inflation with helium, or air (via an electric pump or hand pump). If using helium, hi-float can be injected before inflating for much longer float times. Works well in balloon arrangements, balloon bouquets, balloon columns, and other balloon decorations.
