Our replacement tumbler lids are crafted from premium food-grade clear AS plastic and PP—non-toxic, BPA-free materials that are sturdy, durable, and dishwasher-safe; the thick lid construction also enhances beverage insulation to maintain temperature better. Specifically designed for 20 oz tumblers with a 3.25-inch diameter mouth, they are compatible with models like Yeti Rambler, old-style RTIC tumblers, and most other similar tumblers or cups, and also fit 12 oz coffee mugs. Featuring a special spillproof design, they include a silicone stopper that boosts leakproof performance and stays secure when the lid is opened, along with a unique vacuum-sealed airtight structure to keep your beverages warm or cold for longer; the flip-top part of the lid has a wide-mouthed sip hole, solving the issue of the lid touching your nose (a common problem with older lid designs). Equipped with a unique double-sealing design, these cup lids effectively prevent water from leaking out, and the built-in air hole is sized to fit 6-9mm straws for added convenience.
