The Lube Tube is a two pack of syringe-like lube applicators that allow you to apply your favorite lube exactly where you want it. My favorite use for it is assuring enough lube is applied internally before anal. These also reduce mess by keeping lube off your hands, sheets etc. The cons are; you can't sterilize it (plastic); it is too short to reach the bottom of many bottles; hard to mark/label (to tell one lube tube apart from the other); and they can suck in air. I completely swear by these!
