2 Pack Silicone 40 oz Tumbler Flip Straw Lid Replacement Compatible with Stanley Quencher, Replacement Lids for Stanley Tumbler, Spill Proof Splash Resistant Tumbler Lids for Stanley Cup (White)

I’m happy to exchange a plastic lid for this silicone one.The color is a creamy white, not a tight fit but a leakproof one.Dishwasher safe and easy to care for.I would buy more in different sizes.

Fits easily in my (non-Stanley) tumbler. When installed correctly, it doesn't leak! I used a metal straw instead of the plastic straws that came with it and it works great. The thick silicone seems to actually insulated pretty dang well - I still had ice in my cup two days after filling it!My only real complaint is that the silicone sort of attracts hair and dust - since I live with a bunch of pets in the desert, you can imagine how often I'm cleaning hair and dust off of this lid, LOL!
