Hey I ordered this off the store and I'm jw how wide the diameter of the tube is and the bottom of the beaker is (the widest part). In the details it says its diameter is 50mm and I'm assuming that's referring to the top of the piece where you place your mouth. Any help is appreciated I want the measurements to properly determine how big it'll be and how to hide it if need be.
