9pcs Rose Quartz Stanley Cup Accessories Set | 6 Pcs Silicone Spill Proof Stopper, 2 Pcs Straw Cover Cap for 9-10 mm Straws, 1 Pcs Silicone Boot for 40oz & 30oz Tumbler

Nice set of accessories with a perfect color match. I was honestly surprised at how perfect it was. The boot fits perfectly-- I have tried another set of accessories where the boot was too big for the 30 oz tumbler. The flower straw topper on this set is a little loose but no big deal since I'm not depending on it to be airtight, just adorable. I also like having variety between the plain straw toppers and the "cutesy" ones. The inner leak stopper is actually so airtight that it's weird to drink through the straw with it on, but it does the job it says it will! I've bought another set to match my other Stanley since this was such a good deal.

My favorite part is the bottom cover. It fits perfectly and both protects the bottom and is anti-skid. My husband's favorite part is the mini bottle topper thing that sits on top of the straw because it's so cute. The seals work very well and do in fact prevent spillage.

These work really great to prevent leaks. Using all of this, I can hold my cup upside down without it leaking! Super cute, super great! Good silicone material too!

They are adorable & they keep my ice water cold & they are so durable the size is right the colors are vibrant.

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).

They work well and are cute

I like men them for my cup. Guess other people did too , took my bottom cover off at work It fit good on my Stanley cup

My daughter loves it

The cup cover isn’t rose gold but pink. Other accessories are true rose gold

The 2 pieces for the straw to go in to prevent leaks were not sent. Everything else is great.

Not super durable. The toppers quickly broke along with the inside peice to help slow leaks.
