Betallatex Link-O-Loon Balloons are a quick and easy way to build impressive decor. The balloons have two tying places, one at the bottom (neck) of the balloon and one at the top (tip), allowing balloons to be tied together, creating an arch or column. Link-O-Loons are great for creating various types of structures without the use of monofilament line or other framing materials. These balloons ship uninflated and can be filled with air or helium.
