This is an outstanding drink lid for 40 ounce insulated stainless steel tumblers with threads. Great color and size, good value for the price. It's leak proof but the most important thing I want to say for those who want to convert their Cirkul 40 oz tumblers into an ordinary tumbler suitable for water, home-brewed iced tea or other drinks - this lid is 100% compatible with the Cirkul 40 oz tumbler. If you don't want to drink sucralose in your drinks know that there is an alternative. Cirkul makes great tumblers but opinions are very mixed on their drink pods. Have to note that this is NOT a press-in lid - it is threaded, just like the Cirkul tumblers and I believe Stanley 40 oz tumblers are also threaded. This is a great alternative and a very good product. Kudos Fabenyok! Read more

These replacement lids have proven to be a perfect solution for my broken Stanley lids after they were damaged in a fall. They fit securely, prevent leaks, and restore full functionality to my tumbler. I appreciate how durable they feel, and the smooth opening and closing mechanism makes sipping easy and convenient.

Toddler dropped my Stanley and busted the original lid and these replacements work great. Fit perfectly, honestly feel like a better quality because they’re new and not all stretched out at the straw area. I’d not say they’re leak proof, but I don’t think the original lids were either. Not a deal breaker. Read more

It fits, and it functions as it should. Great price for 2 lids. Looks good. Be aware that it is NOT leak proof, but it’s better than the original from my non-Stanley mug. Read more

I broke my lid to my 40 oz Tumbler so I went searching for another one. I'm glad I found it own amazon. It fits perfect. Now I can use my cup again. Read more

As I am prone to dropping stuff I broke my original lid. Snagged these replacements glad it’s a 2 pack. The color went perfect with my cup and straw combo. The size is exactly correct for the 40 oz Stanley. I will say the type of plastic does make it easy to crack when dropped or hit accidentally with something. I broke one lid somehow in the dishwasher- it must’ve gotten hit with a pan or something. But overall it’s a reasonably priced replacement when needed. Is it the absolute best quality? No but it isn’t the worst. I’d buy it again. Read more
