Work really well for me since I have a habit of knocking over glasses. Nothing spills out. I call it my sippy cup.
These are the absolute best mason jar drink lids! I bought one years ago and it has held up remarkably through the dishwasher and continual use ever since. No rust or wear like many other lids I have seen online - in fact, it basically still looks new. I’ve started drinking more water recently and wanted to buy more lids, so coming back to Simply Straws was the obvious choice! Highly recommend these and all of their products for unbeatable quality.
These lids work really well! I definitely recommend them. The silicone around where you insert a straw helps to prevent metal/glass straws from making clanging sounds. Also, the seal on the inside of the lid helps to prevent leaks.
I use glass for most of my storage and portable beverages, so these lids are perfect. They really help reduce spillage and wash nicely in the dishwasher. 5/5 have bought before and will buy again. Note to seller-replacement gaskets would be something I’d buy.
Amazing straws, totally different quality level than the cheaper ones I found elsewhere. Lid fits perfectly and doesn't leak without a straw in it. None of the other lids I have didn't leak
Love these wide-mouth mason jar lids! Now I can take my preferred drinking glass, my quart-sized mason jar, with me out of the house. And I can use whichever straw I have available-glass or stainless steel. So convenient!!
These are the best reusable straw lids I’ve found so far. Easy to clean, and they fit the thick smoothie straw that I prefer using.
Pretty and functioannl
This is my second lid! I found my first at a zero waste store and since then I'm in love with them.
It fits perfectly on my wide jar. I love it, & now with 2 lids I have a backup. Thanks again.
Great quality, better than other lids that I’ve tried
As usual, the quality of these lids is perfect. It’s exactly what it should be. I made a half mistake in ordering and I got a few freebies. They seemed to know what I wanted, even tho I put the order in wrong. Very insightful.
I was also a bit rude, as I can be, and I was still treated exceptionally. Fine company to do business with and fantastic products.
Okay
We love the lids! We have been using them for smoothies. Great for travel.
I have had my lid for a couple of weeks now and I love it. It works perfectly with my normal width and wide width simply straws and the silicone gasket holds both my straws snugly in place.
Love it!
One of the best kids that exists!
A practical, spill-proof way to stay hydrated every day.
I love my new lid, Thank You!
Finally found something I always wanted! I love it!
Great sturdy straws, pretty colors
This was my second purchase of the Mason straw lid, I have many of their straws and now I have a backup lid if one is in the wash. Fits really well on my Ball quart Mason jar, keeps me hydrated during pregnancy!
They work beautifully!
Very happy
Love it!!
I've been wanting to buy this for awhile now. I love the stainless steel. It fits my Mason jar perfectly
Both lids should have straw holes
It’s attractive and functional.
Super easy to clean and I don’t hve metal rubbing against glass with the grommet it had in the middle, thank you
Love it!!
They are great. Nothing leaks. Easy to clean.
Love
