I'm a purist when it comes to fine liquors: I don't like to water them down with water/ice and so drink them neat. That said, I don't "do shots." I like to savor mine. These soapstone shot glasses are good for both purposes, however, whether you like to sip or throw it back. I store them in the freezer to give the alcohol a little chill.
Each "glass" has a 2 ounce capacity, the equivalent of two shots. They are made of soapstone-- a smooth, nonporous material that can freeze without cracking and that doesn't absorb flavor so that each shot (after washing) tastes pure. Right out of the freezer, they don't stick to skin; they also feel cold but not frozen. Don't expect these glasses to substitute for ice. They chill the liquor a little, but don't make it cold.
I notice that the product photograph shows a bottle of sake, and that's funny because that's what I thought these were before I saw the photograph: sake glasses. They have that simple, earthy design that sake glasses often have, unlike the usual Western crystal for whiskeys. I suspect that they've been re-labeled for American drinking habits. If these were really designed as sake glasses, then they should take warmed liquor as well, although I wouldn't recommend pouring warm sake into a frozen shot.
These make a great gift for the liquor-purist who has (most) everything.
