Those that like to drink their liquor in 2 ounces or less know the pain of being next a bottle of tequila with no shot glass in sight. Don't fret as this collapsible shot glass has got your back.
The 1.7 oz. cup has everything you need. It squashes down to a portable size, includes a cover to keep it clean, fits nicely in a pleather travel case and even has a clip so you can attach it to your key chain. And it only costs $US16. Yeah, baby. [Magellan's via Foodbeast]
