gas level indicator-special shape

Even been caught short with an empty gas cylinder unexpectedly? Afterall, there's no way of tellling how much is left and it can so easily run out halfway through a barbecue or much worse, on a cold winter's day when you're using the gas heater.

Just place the GAS LEVEL INDICATOR on the bottom half of the cylinder and once the gas is switched on, the color of the bar will change below the liquid lecel telling you how much gas is left.

It's safe, non-toxic, easy to use, reusable and unbreakable.
