This nuPROTO hand soap attachement goes underneath the soap dispenser and around the tube. This prevents the pump to go much further down. It gives you enough soap to wash your hand and if you need more.. you pump twice! This will save you a lot of green. Less soap and less waste is also green. So now you can enjoy your nice scented soaps. Without worrying about your kids, visitors or yourself wasting money down the drain.
