Fit perfectly on my 1.5L bottle of Listerine!
Fit perfectly and is very helpful in my bathroom.  2 pumps is all you really need.  No mess and no wasting.  The family can easily get the right amount with out wasting or spilling the mouthwash anymore.  The best part is no one can use the cap anymore, much more sanitary.  I am a happy mom over this little purchase.
