4 WIDE 40-Ounce Stainless Steel Straws (NO CUP) for 40 oz Ozark Trail Double-Wall Rambler Vacuum Cups - CocoStraw Brand Drinking Straw (4 Straws 40oz)

Bought thinking it would work with my Stanley. Too small by about 1 inch. It works ok. Just wish it was longer.

Exactly what I was looking for!

These are nice straws, fit my 40 oz tumbler perfect. However, they are not wide at all. I will use them, but it does make drinking my morning smoothie's harder.

I got these fir my 40 ounce Stanley cup and they are too short, they barely poke out of the opening

Just not tall enough for the Stanley 40oz cup, so I used my rubber ended straw protector lower down the straw near the cup lip so it couldn't slip down enough and stay up. Brilliant .... I know

They weren’t the ones I wanted I have the new ones coming hope hopefully Sunday

This doesn’t fit a Stanley 40oz cup and the straw is not wide. Bummed!

If you are buying to match - buyer beware. The one I got has too narrow of an opening. Seems like this is actually an older style, but I bought them both at the same time. So maybe the blame is more on the cup sending me and older style - but it is exactly the one linked here on Amazon.If it fit, I actually really like these straws. In fact, I am not returning them because they are good quality and I like them stylistically- but since they are advertised to pair and that is what I bought it for, I am still not satisfied.
