Flat/flexible oil funnel.

[Moab]

This seems like a fairly simple invention. It's just a flat peice of flexible plastic that allows you to get fluids into odd places on an engine. 

But in the context of bugging out or using this in the field - the real advantages over a traditional funnel is it stores flat. But the real advantage comes after you use it.

A traditional funnel will be left with oil or other fluids left inside of it. If you've ever used one you'll know how messy that is. I've placed them in plastic bags after. But then your left with an even bigger mess. As the oil slowly leaks out and covers the entire funnel inside the plastic bag.

With this simple peice of plastic you just wipe it off. And place it back in your tool bag. 

This isn't the best price either.
