Be cool.
These are made for booze (whisky specifically). And they’re great for that. If you’re into whisky, absolutely worth a try for the price.
But it turns out that a cup that’ll keep your whisky cold without watering it down will also keep other stuff cold without watering it down. We’re talking about pretty much anything that you don’t want to put ice in, like a smoothie or maybe a soda that you want to nurse for an unusually long period of time.
They’re great—super satisfying to hold and to use, plus not bad to look at. Oh, and definitely easier to keep clean than those whisky stones that some people buy.
Four bucks a cup!
