Pair of 500 milliliter Pyrex Erlenmeyer flasks stacked and held together by a wood veneered cuff. While the intended purpose is unclear, they were found configured this way in the bar setup of a chemist’s estate, making them an eye-catching piece of scientific bar decor. One of the flasks has Sharpie writing on the bottom, as shown in photos. Great for vintage science enthusiasts, bartenders looking for quirky decor, or anyone building a chemistry-themed space.
