This is 10ml of high-quality lithium grease in a syringe that actually lets you put grease where you want it instead of everywhere except where you want it. The blunt tips mean you can inject grease into bearings, rails, and tight spaces without making a mess or stabbing yourself. It's a good quantity; enough to last through several printer maintenance sessions, small enough that you won't feel bad when you inevitably lose it in your workshop.
Speaking of which: This product offers ZERO protection against disappearing into the black hole that is my workshop shelves. I didn't dock points for this because that's a "me" problem, not a grease problem.
