The grease is RMB branded Marine grade water proof (looks pretty generic like all marine grade stuff) and comes in its own plastic bag in the kit. You can see it in the pic of the grease gun in the case on the right hand side of the grease gun. Green bag. You have to put the grease in the gun yourself.
That looks like a generic small tip grease gun from amazon I think I got mine for $15 and the link for my altitude was $100 (all USD) that's $50 to your local shop. I hope they installed it for that.
