8Pcs Straw Covers Cap for Stanley 30&40 Oz Tumbler, Cute Silicone Reusable Tips Lids for 10mm(0.4in) Diameter Straws. Straw Toppers Stanley Cup Accessories, Dust-Proof Plugs Cap Protector

I really like the different designs of these straw toppers, so everyone can tell which drink is theirs if they have similar cups and straws. I got this because usually bees and other bugs try to get into my drink when outside on a hot day and I thought these would be perfect to fix that issue. It has been working great so far and I'm really glad I got them, I don't have to worry about anything getting down my straw now when I walk away from my drink.

These silicone straw caps are cute and practical. They fit my 40oz tumbler just fine. They are initially snug fitting but after some time they loosen up. They feel durable and I love the whimsical look of them.
