Here's what you should know about Helium Gas.
All our balloons are air-filled. We no longer use helium gas as there is a worldwide shortage of the gas which is more direly needed in the medical & scientific world. Here's an article that you can read about it here. There are lots more articles on the helium shortage that you can read about on the internet - just ask Google!
But don't worry, your balloons will look just as good as if they were filled with helium - we prop them up on a pole so it'll look like they're floating! What's better is that they'll 'stand' way longer than if they were filled with helium. A typical 'float' period for regular balloons are about 4-8 hours in our weather. With our supports, your balloons will be standing until they completely deflate, which could take days and, for some, even weeks to months!
*CAUTION* We would caution you about the current sale of helium filled balloons. As helium gas is more expensive now (due to the shortage), the cost of your helium balloon should be a little pricier than it once was. If it isn't, do be wary as the gas used may be mixed with (or be entirely) a flammable gas such as hydrogen. Here is one occasion in Malaysia where many were injured due to this: https://www.nst.com.my/news/nation/2019/10/529789/balloon-explosion-it-was-hydrogen-not-helium
