潤滑液注射器藍色

The plunger makes it so much easier to get lube exactly where it needs to go instead of guessing with fingers. I keep it in the nightstand and it's cut my cleanup time way down.

Finally no more lube ending up everywhere except where I need it. The plunger gets it right where it belongs, and cleanup afterward is basically nothing. Just wish it held a bit more per fill.

Getting the lube exactly where you want it instead of on the sheets is the whole point, and the plunger does that job well. Only gripe is that it takes a bit of practice to load without making a mess on your hands. Solid little tool once you get the hang of it.
