Rabbit Chrome Chilling Stones
Hmmm. These aren't the Rabbits I've heard of. The Rabbits I've heard of do not insert into glasses, and in fact deal in the complete opposite of making things cold. I guess Rabbits are multi-faceted.
These Rabbits are of the Jumbo Chilling Stone variety. Stick them in the freezer for a few hours and then add to any beverage or cocktail you want to keep chilled without diluting. Stones are made of stainless steel and designed in size Jumbo to avert accidental swallowing. Accidental tooth bashing: still a risk. They are sold in pairs, with each Rabbit big and cold enough to chill a drink on its own.
