You can take it with you! If you frequently need a shot glass in a pinch, the Telescopic Collapsible Stainless Steel Shot Glass Key Ring is your new best friend. It folds up into a small disc you put on your keychain and when you need a quick shot just unfurl it and down the hatch. It could also work as a medicine cup or kid’s cup too I suppose. Or a “medicine” cup as in I need my “medicine” now, pour me some Jack Daniels. Super handy.
