Protective Boot and Spill Proof Stopper Set for Stanley Cup

10/10 recommend. Stanley should be ashamed of themselves that we have to purchase items like this to keep the cups spill proof - DO BETTER STANLEY!! Any who - these accessories fabulous. They are thick and keep everything sealed. Great quality! These accessories fit any size - the cup doesn't have to be a Stanley!

Does exactly as advertised. I was so sick of my Stanley leaking, but this seals it tightly. I also like the extra pop of color. The boot fits just fine. It was all very easy to install.

These accessories fit my Stanley perfectly! The silicone pieces prevent leaks, and the straw covers are great for keeping things clean. Fun colors and great quality! 💖

I have never been fond of any of these tumblers but found I am always struggling in car with other types of drinking containers with spillage and moisture causing issues. Therefore I tried the Stanley with the accessories to hopefully prevent further frustration. What a great accessory!!! I absolutely love love love the addition to this tumbler preventing any leaking, moisture and spillage!!! Now if I can just get used to using this huge 30 oz cup and a straw which I despise using straws. Adjusting soon hopefully because I have omitted some of my problems with these accessories. Great Item!!!

If you already own a STANLEY Quencher tumbler, you know how great it is — but also how quickly those small parts can go missing or wear out. That’s where this HYZ 8 Piece Accessories Set comes in handy. It’s not flashy, but it’s one of those practical upgrades that quietly improves your daily routine. What’s Included: The set typically includes silicone straw covers, spill-proof stoppers, a protective boot, and extra straw tips. Everything fits snugly on the STANLEY Quencher H2.0 models (check your tumbler size before ordering — this set is made for the 30 oz and 40 oz versions). Performance and Fit: Each piece feels durable and well-made. The straw stoppers create a tight seal that prevents leaks when the tumbler tips or rides in the car. The straw caps keep dust, lint, and mystery particles out — especially useful if you take your cup to the gym or outside. The protective silicone boot at the base is the hero here: it absorbs noise when setting the cup down, protects from scratches, and adds a nice pop of color. Ease of Use and Cleaning: All the accessories are dishwasher-safe and super easy to pop on and off. The silicone is thick enough to feel sturdy but still flexible enough to stretch without tearing. Style and Color Options: The color options complement the most popular Stanley tumbler shades — whether you’re into muted tones or bright, bold pops. Mixing and matching adds a bit of fun personalization without looking cheap or clunky. Downsides: Some users may find that the straw covers fit a bit tightly at first, and the boot can trap moisture underneath if not dried properly after washing. It’s not a dealbreaker, but worth noting. Overall Impression: The HYZ 8 Piece Accessory Set is a surprisingly valuable addition for Stanley owners who want to protect their investment and make their cup even more functional. It’s affordable, practical, and adds a layer of convenience you didn’t realize you needed until you had it.

Fits my 30oz Stanley bottles & matches the hydrangea color perfectly.

This HYZ 8 Piece Accessories Set for Stanley Cup is great! The silicone stoppers really do their job—no leaks even if the cup tips over. The protective boot is a nice touch too, keeping the bottom from getting scratched or dented. Everything fits perfectly and adds extra peace of mind when I’m on the go. Highly recommend for anyone who wants to keep their Stanley clean, protected, and spill-free!

So my daughter just had to have a Stanley for her cup for school last year. We have literally about 30 different cups for the kids to use for school from Hydro Flask, to Yeti, to Under Armour,Gatorade, Nike and many other name brand and off brand tumblers. However, something happened last year and Stanley became a big deal with the kids at school and she was actually being picked on over not having a Stanley brand cup like a lot of the other kids in her class (kids are ruthless). I told her that the cups she's been using cost way more than a Stanley and to not worry about it (but I always bought those super expensive cups when I'd see them in clearance and get them for 75%-90% off and buy several of them, I just never understood spending $50-$90 on one tumbler). But that didn't matter to pre-teen kids, if it didn't say Stanley, it was trash and you were "poor" (we are a middle class, blue collar family, stuck in a white collar school district, so we always save up before the school year starts so the kids don't go to school looking different from the other kids, and it's hard when the economy isthe way it is and you're living paychecktopaycheck). So we broke down and bought a $40 Stanley, and after using it twice, she hated it because she couldn't just throw it in her backpack like her other cups, so she stopped using it and would take it to school every great once in a while to "prove" she had one so the kids would leave her alone, but her dad and I were pissed we wasted money on a cup she really didn't need. So when school started this year I seen this and bought it to see how well it worked, and it truly does keep the cup from leaking and it's cute. So she's been so excited to be able to use her Stanley everyday and has taken it to school daily without any problems. She says the other kids in her class have asked her where she got it and a few have went out and got some for their cups too. And dad and I are happy we didn't have to waste money on a new cup this year.

El color claro es más bien blanco. La calidad del material es la que esperaba. Si evita que se derramen los líquidos. Funciona bien para Stanley de 40oz.

Perfect colour match and made cup completely watertight. Exactly what I needed

Dosent stop leakage. Useless.

10/10 la calidad, color

Contente du produit reçu, s’adapte très bien sur une stanley 40oz
