These Himalayan shot glasses let you take your tequila shots without the salt shaker handy, as your tequila comes already salted: The longer you leave your tequila in the glass, the saltier it gets. Himalayan salt has been left untouched for millions of years, so it's believed to be the purest form of salt in the world. Our set of Himalayan shot glasses makes a great gift for any tequila aficionado.
