As a chemist, I have a weakness for laboratory glassware or items that even mimic labware. This set of Jigger Bottle Stoppers caught my eye, because they combine barware shapes – whiskey glass, snifter, hurricane, and martini glass, respectively – with a labware feel. Measurement markings both add to the lab feel, and they serve as handy measuring guides for mixing drinks when you use them as jiggers. You can even use them as shot glasses, but I’m not sure how you’d ever set it down when the drink is gone. And when you’re done tending bar, they can be used as bottle stoppers for your potent potables. The jiggers are made of glass, and they have a silicone stopper bottom. The set of four Jigger Bottle Stoppers is $19.99 at UncommonGoods.
