5Pc Straw Cover for Stanley Cup, Silicone Straw Topper for Stanley Cup 30&40oz with Tumblers, 10mm 0.4in Lid Accessories (Reusable)

I had purchased another of these and they did not fit my straw. I found these and tried them... to my surprise they are great, unlike the first ones i bought (that are NOT this brand!) The colors are vibrant, the designs are so cute! They fit my Stanley straws as well as my Reduce straws!

No more fruit flies diving down my straw. They fit just fine, good price, cute.

It’s so cute and has many colors, you can always change it and it’s easy to use. It’s convenient and fun, nice portability. Fits exactly good on a Stanley.

Fit perfectly, cute, and cost efficient

These work great for my Stanley! They're so cute, I love all of the options (I'm a color matching girlie so the multitudes of styles and colors are a plus), and are fairly durable.My only complaint is that initially some of the rubber material flaked off on/in my straw when I first put the topper on it so i had to scrape the inside to make sure that no more got in, and that the inside where the straw goes is a little difficult to clean. The gunk from the straw gets into the hard to reach area inside of the topper, so a straw cleaner is required to get it actually clean.

Love these! They're fun and cute. They protect my straw. They actually fit the small and larger straws. Easy to clean.

They fit the Stanley straws perfectly and stay on. They’re adorable!!

Fits and functions on the straw as expected. Very cute designs and durable. Would definitely recommend!!
