FOWEROTY 12-Pack 0.4in/10mm Straw Toppers, for Stanley Straw Covers Cap for Tumblers for Stanley 30|40 Oz Cup, Silicone Dust-Proof Caps（ Cup is Not Included）, Multi-color

Perfect fit for my Stanley cup straw. Durable and love the colors.

My custom tumblers didn’t come with straw toppers so these were exactly what I needed. They fit perfectly and are of a good quality. If I need more, I’ll definitely be buying these. My straws were standard size so these fit perfectly.

Got this for my new Stanley cup...fits perfect..very cute...seems sturdy...great value for what I paid for it! I want to buy more now!

Works perfectly on our forty-ounce Stanleys.

Was hoping it would fit over the end of my Ozark trail cup straw. It does not fit over the flexible end of the straw. It does fit over the hard plastic straw. The colors are pretty and bright. I would have given it 5 stars if it fit on the flexible straw.

Great straw toppers. Just what I needed. They fit my Stanley straws perfectly.

I love it. Nothing gets in no get in my drink. It's the most useful, and awesome thing have bought.

Good quality and fit to be universal. Used with multiple tumblers from different brands.

Yaaa çok tatlı durdu içini dışını heryerini koruyor çok memnun kaldım
