Bellos me encanto casa pueda

Excelente calidad. Tal cual en la imagen

Great collection and has everything I ever wanted for my Stanley. The waterproof cap does an amazing job. The base holder helps it keep safe from denting. The only downside was the floral straw which is very loose. Rest everything was just perfect. None of this has after use taste.

Great purchase. Good price.

Such a fun design. Fits nice too

Yes, I know it's not baby Yoda, but sometimes I forget how to spell his name. :) But they are super cute and people notice them when I use them on my straw.

Edit: the round leak stopper that goes on the inside has the TINIEST air vent. So no liquid can come through, but it took a couple of washes and accidentally jamming a small cleaning brush through the hole for 1) me to realize it was there and 2) for it to loosen up enough for it to actually function in preventing the creation of a vacuum seal on the inside while drinking. Now my drinking experience is both mess-free and much easier. Just took a little breaking in and lack of observation on my part for it to work as intended. Update to 5 from 4 stars, and my original review is below to show the progression of my opinion of the product.I did the flip test on a full 32oz Stanley, and it held excellently! The straw topper is a tiny bit looser than a different topper that I have, so I have more concern about it popping off if it gets knocked over than with the other one (different purchase). But! The leak guards for the lid itself create an excellent seal! So much so that a little vacuum is created each time I take a sip since there is no longer any place for air to vent back inside while I'm drinking. Not a problem for me since I'm a sipper and not a chugger! But it might be for you if you take big swigs like my husband does. Now I won't be as anxious about my drink decorating the living room if my toddler gets a hold of my Stanley anymore.Also, the boot is really nice. My cup doesn't have the signature metallic thud when it set it down anymore (that I hated).
