【Perfect Compatibility】: Compatible with 40oz Stanley tumblers (and similar-sized cups), this replacement lid snaps on snugly for a seamless, hassle-free upgrade. Note: Lid only—tumbler not included. 【Upgraded 2-in-1 Design】: Different from typical lids, our tumbler lid offers both a straw and a sip opening, allowing you sip through the flip-up straw or drink directly from the mouth opening—ideal for both cold drinks and quick sips on the go. 【Dustproof Flip Cover】: Our new flip straw lid is designed with a cover, keeping your straw clean from dirt and germs when not in use. Keep your straw clean wherever you go—great for commuting or outdoor use. 【Leakproof & Secure Seal】: Our upgraded silicone lid creates a tight, spill-proof closure, so your drinks stay put—whether you’re tossing it in a bag or taking it on adventures. 【Easy to Clean & Durable】: This replacement lid is made of premium silicone, BPA free and durable. It is detachable and easy to clean. Dishwasher safe for low-maintenance convenience.
