Drink Like A Mad Scientist

If you lose sleep keeping track of your daily intake, have we got 2-in-1 special for you! This handy 500mL clear glass beaker mug not only proudly proclaims that it's for caffeinated beverages only, but it also has 50mL graduations to let you know just how much you've consumed. The front has the molecular symbol for caffeine, and is labeled as such for the non-chemists out there, while the back has the graduations, from 200-400mL. At 4-3/4" tall x 3-1/2" diameter with lip around the top it's a smidge taller than a normal mug and not intended for serious lab work as the volumes are approximate.
