Sometimes you need a tub of grease.
But more frequently you just need a little. A few months ago I bought myself a Dualco 700231 Grease Gun and a Dualco 10547 4.5” nozzle. I filled the gun from a tub of Phil Wood Waterproof Grease that I’ve been working through for a handful of years. This made servicing my pedals much easier and less messy than previous jobs. Purchases like this make me feel more like an adult.
