This liquid soap sensor pump is an efficient way to wash your hands with no germs or smudges left behind. The clog-proof tubing ensures a precise and consistent flow, and the silicone valve prevents messy drips. A funnel refill opening makes refills fast and easy, and it's waterproof for easy cleaning. To control the amount of soap desired, you can position your hand up close to the sensor for a little soap and farther away for more.
