Helium valves are great for use with latex balloons up to 12". They simply fit in to the neck of the balloon before inflation, no need to tie a knot! (saving fingers and time). They have a metre of white ribbon attached which spirals out once the balloon is inflated with helium by pulling the end, releasing the tab. Valves are not biodegradable and therefore should not be used in balloon releases. WE DO NOT RECOMMEND USING VALVES WITH DISPOSABLE HELIUM CYLINDERS. |
