Orbz balloons are much more different than standard balloons and supershapes. They are four sided balloons that form into an almost perfect round beach ball shape. They provide huge impact and really stand out. They can be inflated with air or helium and have a self-sealing valve. Cannot be fully inflated with a straw and breath alone. The balloon needs to stretch to form and requires more power from an electric inflator, balloon hand pump or helium regulator. If inflating with helium, it requires the latex valve to be used. The latex valve will provide enough force to fully inflate the balloon. Please note that during inflation, it may make a popping or cracking sound as it expands. This is from the seams seperating and should not alarm you that the balloon may be popping. Fully inflate until all the wrinkles are gone and the balloon is perfectly round.
