2PCS Tumbler Flip Straw Lid Replacement Fit for Stanley Quencher 40 oz, Leak-Proof, Straw Lid Replacement Fit for HydroJug Traveler,Reusable Tumbler Cover (Green)

I love these lids and have purchased four in total. They don’t leak, which is the reason I got them. They also fit my 40 oz perfectly. I know a lot of people have difficulty cleaning them but there’s actually a pretty easy fix. If you close the valve all the way, you’ll see a little hole on the back. Using a tiny Phillips screwdriver (like the kind you might get in an eyeglass kit), gently pop the valve out. Inside there will be a small clear flexible gasket—don’t lose it! You can clean these items and then easily pop the valve back in place. I usually like to give everything a soak in bleach every few weeks.

Did not fit my hydrojug.

Doesn’t leak and a great price for 2. The color matches my Stanley cream color I had. I’m happy they match. They are pretty easy to clean as well

Did not fit my Hydrojug 40 ounce cup but does fit my Stanley 40 ounce cop. I will try to find the ones that actually fit the Hydrojug. Works good on the Stanley.

This does not fit my 40 ounce hydroflask, they are good quality just incorrect ones bought. I still kept them though because I have other cups they will fit.

Pros: - You can tip the bottle any way and zero water leaks out. - better straw placement than on the Stanley brand lid. Cons: - after a short period of use, the lid has black mold in spots that can’t be cleaned, rendering it completely unusable - the seal on the second lid ripped within days of use so now I have no lids left

I had picked up a Thanksgiving clearance Hobby Lobby Stanley style cup with no lid for $2. I picked these lids and hoped they would fit. They were perfect and I couldn’t be happier.

Nice product. It doesn’t fit my Stanley. It screws in bit but the threads don’t fit. I struggled to get the lid off. Returning it.

Leak-proof and fits our two different brands.

thank you, your product is amazing. Even the delivery was delayed due to canada post strike. you are so kind to give me a refund. not only that, the lid works perfectly on my stanley! good seller, good product, highly recommend, thank you!

DO NOT BUY! Does not come with a straw. Also does not fit. Poor quality. And they’ll make you pay for the return label. It’s a scam!

I bought this lid but it doesn’t fit properly; too tight. I found a better lid by measuring the internal diameter of the Stanley Cup. The right lid should be 9cm / 3.54 inches.

The lid doesn’t fit correctly on a Stanley cup due to this the item is not leakproof
