BonneChance Lilac Silicone Stanley Cup Accessories Set: 6 Pcs Spill Proof Stopper, 2 Pcs Straw Cover Cap, 1 Pcs Silicone Boot for Stanley 40oz & 30oz Tumbler

I got these pink accessories for my Stanley cup and they’re both cute and super practical. The soft pink color is beautiful — subtle, not too bright — and it adds a fun, personal touch to my tumbler. Everything fits perfectly, from the handle to the lid and straw topper.The quality is great — nothing feels cheap or flimsy — and it definitely makes my Stanley easier to carry around and keep clean. I’ve gotten so many compliments, and honestly, it just makes me happy every time I use it.If you want to personalize your Stanley and keep everything coordinated, this pink set is totally worth it.

I love how these accessories match my Stanley cup. I get lots of compliments on my cup. I also love that these accessories prevent my cup from spilling water. I’ve included a photo of the cup turned upside down and it was full of water at the time. It works great! The key is to read and follow the instructions when installing the part that prevents spills. It was easy to install but I can see how someone might not do it right if they don’t read the instructions.

How cute is she??? This set fit my 40oz Stanley x LoveShackFancy tumbler perfectly & made it 99% leak proof.

I bought this set mainly for the boot for the bottom of my Stanley and the cute straw toppers. When I saw it came with 2 pieces that make the cup spill-proof, I was sold.The boot is a perfect fit and color to match my rose quartz tumbler. The toppers are adorable and functional.But the pieces that fit in the lid to make it spill-proof makes drinking an embarrassment. I should have known that spill-proof also means airtight. So when I suck water out of the straw and take my lips away, the vacuum that is created makes a loud thud as the pressure is equalized. That may be fine if you are at a concert or festival where you can’t even hear yourself talking. But for everyday life and out in public where people can hear you, it’s cringey. The pieces are not easy to take off, either. So it’s not like you can just pop them in and out when needed.Other than that issue, I am happy with my purchase.

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).

LOVE THESE!! They are super cute, functional, and keep my straw clean. The color matches my Stanley perfectly. Great quality, too!

Super cute! Great quality, perfect size for the straw!

Love these accessories for my Stanley! They are so happy and great quality, fits perfectly and no spilling at all!
