This lube feels like silk. It's smooth. It's slippery. If you were to sit down with a think tank and devise the ideal lube, it would feel like this.

It works like this: You squirt it on the holes you want to slide things into, and then you're able to slide them in. Easy peasy! Seriously though, it is super easy. It's thick, so the lube stays where you put it. Don't need to worry about gravity taking it places you didn't intend.

The lube container itself is standard container size.
As far as measuring out how much lube to use, that's totally up to you and the job you're using it for. I will say a little goes a long way, so you don't need to overdo it. But again, use how much you need and not a drop less. Maybe a little more.
