They fit my Hydro Flask tumbler perfectly and stay securely in place without constantly falling off. They do exactly what they’re supposed to do by keeping the straw clean, while also adding a fun, stylish touch to my cup. The designs are adorable, and I love that the pack comes with several different options so I can switch them out depending on my mood. They’re made from a soft, flexible silicone that feels durable and is easy to put on and take off without stretching out. They’ve held up really well with daily use. One thing I didn’t expect was how many compliments I’ve gotten on them! They’re a small accessory, but they really personalize my tumbler and make it stand out. The only minor downside—and the reason this isn’t really a “perfect” product—is that my husband isn’t a fan of washing them in the dishwasher because they’re small and can be a little fiddly. That’s more of a convenience issue than a problem with the product itself, and I personally think it’s a small trade-off for how cute and functional they are. Overall, these are a great purchase if you own a Hydro Flask or compatible tumbler. They fit well, look adorable, help keep your straw clean, and are an inexpensive way to add a little personality to your favorite cup. I’d definitely buy them again!
