9Pcs Straw Cover Cap Topper Dust-Proof for Stanley Cup 10mm/ 0.4in, for Drinking Straw Cap Stanley Cup Accessories, Cute Silicone Tips Lids Dust-Proof for Water Bottle

This was a fun addition to my daughter's Stanley cup. She carries her cup for many different activities--from walking to classes to taking it on hikes. I feel better with a covered straw. These straw caps come in a fun variety of styles, she likes them and they fit her cup's straw well without issue. We only hand wash them and they are holding up well to daily use.

I want to love these, I really do. The design is so adorable, my kids love using them. However, they are quite loose on all the straws we use, which is a real shame. As a result, they can occasionally leak. The material is nice to touch, and feels sturdy. It's cute, but not completely fit for purpose.

Nice assortment, colorful and great looking, and keep my straw covered from those random germs flying about. Just remember to clean these too every so often. My daughter and her friend took a couple as well since there were more than enough to share with others.

I thought these straw toppers were just so adorable but they are quite loose and don’t fit snuggly on my Stanley straws. It’s a bummer but they do make up for it in cuteness, just not function.

These toppers are adorable! They are brightly colored and fit well. A great idea to keep your straw covered and to be more sanitary.

These high-quality and durable straw covers are perfect for a 10 mm straw which is the same size straw as a 40 ounce drink will usually come with. The colors are cute and pastel and the designs are wonderful.

These straw toppers didn't fit my Coldest bottles. They are on the loose side. Love the concept behind them which is why I'm leaving it at 4 stars.

Disappointed they only fit fat straws but they're cute
