Never seen this type of product in pharmacy stores but it was available on Amazon. It is a quality made product that will come in handy on a trip where rest stops are far and few. My only exception to this product is the design. It would have been desirable if the basic design was that of a "swan",wherein,the contents go right down into the container--a "Z" shape. On my first use, I neglected to tilt it down enough and the contents came back at me. Otherwise, this is a handy product especially on a private plane trip which involves some hours of flight time nonstop.
