Non-Tipping Rocks Tumblers, Set of Two

These are tumblers that moonlight as thermoses. 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.

70% of our planet is covered in water—and Toadfish intends to preserve it. For each of their premium fishing and maritime cooking products sold, they plant new oyster beds, which help filter and keep the Earth's beautiful waters clean.
