【Great Compatibility】 This lid fits 20-ounce insulated stainless steel cups with an inner diameter of approximately 3.15 inches made of any material. Not compatible with RTIC flat-bottomed cups and 20 oz skinny tumblers. To ensure the right fit, measure the inner and outer diameters of your cup before purchasing, and refer to our size pictures for accuracy.
【Safe Material】 Crafted from BPA-free, eco-friendly, crystal clear AS plastic that is sturdy, durable, non-toxic, and dishwasher safe.
【Splash-Proof】 The flat-bottomed cup lid has a silicone gasket along the edge to prevent spills when the cup is tipped.

Please review the precautions before buying.
