Remember the time you brought your beer to the beach and just wanted to relax on your lovely colorful beach chair only to spill some of it onto the sand when you knocked it over. You clumsy oaf! But don't worry, there's a solution.
Turtlebacks are pretty simple—essentially clawed coasters, that'll dig into sand to give your beverage even footing. The alternative to this is of course, hold on to your drink. No charge at all.
