Helium valves (heli-valves) are a great time saving solution when inflating large numbers of latex balloons, particularly for giveaways. The valves are inserted into the neck of the balloon before inflation, and then you simply inflate and pull down the pre-attached ribbon - no need for sealing or tricky tying of the balloons. Valves should never be used for balloon releases. You can buy them loose to fit yourself, or if you are also buying your balloons from us we can fit them for a small charge.
