Large bottle, it will easily last a year or two (I use my machine once a week). A very small spray (it doesn't need much, just enough to cover the blades with a film) after cleaning from hair, and even the sound changes (it runs smoothly, no more stuttering).

It has a spray nozzle (like WD40) and not a dripping nozzle.

It is not thick, and any residue on the hands rinses off easily.

I have no skin irritation.
