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.
Stainless Steel Tumbler Straw Pack
Our Stainless Steel Tumbler Straw Pack includes five 12.5 inch reusable straws in our signature mermaid color and fits most 30oz-40oz tumblers. Crafted from premium food-grade stainless steel, they’re durable, easy to clean, and perfect for iced coffees, teas, waters, smoothies, and everyday hydration.
Swap them in, mix and match, and keep your sips looking cute and feeling clean.
Our stainless steel straws are plastic free, non-toxic, dishwasher safe and environmentally friendly.
