Why choose Mermaid?
Most 40oz tumblers use a press-on lid with an open straw hole. That's why they leak the second they tip in a tote bag or a car door. We built the Flo Tumbler with a screw-on lid, a magnetic seal, and a silicone gasket around the straw, so 40 ounces stays where you put it. Same capacity everyone else offers. None of the cleanup.
