If you're already a hard core Whiskey lover, we don't need to tell you how to drink it (Not that you'd listen anyways...just kidding. Kind of.). But for those that aren't yet Whiskey Glass literate, here's the scoop - swirling the ice ball or liquor itself, releases aromas and flavors in your favorite liquor. The On The Rock Glass & Ice Ball Mould takes out both the guesswork and embarassment of trying this on your own. The On the Rock Glass is specially designed to make rolling the ice ball easy. It cools your drink quickly and evenly without spillage! And the ice ball mould ensures the perfect sized ice for this particular glass. Even better, ice balls last longer and won’t water down your drink!. So put on some Thin Lizzy, and down that glass, the "right" way.
