Made from stainless steel, they sport graduated measurements on the interior—yes that means you can make cocktails in 'em—and a grip on the bottom to keep them from tipping over. Their double wall vacuum construction and shatterproof lids help keep your drinks hot or cold, which you can then sip serenely, knowing Toadfish plants ocean-filtering oyster beds for each and every purchase.
