6 PCS Cute 3D Skull Designed Straw Covers for Stanley Cup 30 40 oz, 10 mm 0.4 inch Silicone Reusable Drinking Straw Toppers

These work good and are good quality.Fit my cups good and very easy to use.Love the look.

These are super cute! I LOVE the bright orange! Skull seems to be thick rubbery material, fit almost all of my straws. Strap has held up well in the couple of weeks that I have been using them. I love them, good price for the quality.

Fits my Hydroflask staw well, nice and snug. No leaks.

These skull straw covers keep dirt and bugs off my straw when I'm outdoors and the design is so cute my son keeps stealing them from me.

Cute colors, stretchy

Fits my straw perfect! I have a 40oz simply modern cup with handle. Love all the colors!

Not a Stanley girl but a Yeti one. These fit nice and snug on the Yeti straws. These are definitely meant only for thicker straws, will work with the straws from Starbucks cups but will not be snug and will come off if commuting with the cup. Works well enough to not have the top of the straw exposed if being used on a cup that stays at work for instance.

While these are super cute and a nice size, they only fit the “chubby/fat“ straws. Think Boba tea straw. I have what looks like a Stanley Cup, but is not (I love it nonetheless, and it keeps my water ice cold, even while sitting out in the sun on my boat) and the straw is too thin for these.
