Naturally, a tumbler with this much built-in functionality can raise a few technical questions. So, we’re always here to tackle the curliest of questions you may have about this absolute beast of a stainless steel tumbler.   

Not seeing your burning BEAST question answered below? No worries -just reach out to us and fire away with queries about anything we’ve left out!   

Chances are, somebody out there has been wondering the exact same thing as you are…   

Here’s the Top 10 questions we get asked about the BEAST from our customers:


10. WILL THE BEAST FIT IN MY CAR’S CUP HOLDER?

Q: What are the dimensions of the bottom of each BEAST? I’m thinking about getting the larger size, but want to make sure it’ll fit in my cup holder so I can take my coffee in the car!

A: Yes! We specially designed every size of the BEAST with a slim, tapered base for that very reason. Each of our 20oz, 30oz & 40oz tumblers all taper down to a slim bottom that measures under 3" (7.5cm) across.

This narrow base was developed to fit in all sorts of standard cup holders for ultimate portability, so you can enjoy your coffee in the car, on the boat and even while in a recliner watching a movie! 

Of course, if your car’s cup holder isn’t a standard size, give it a quick measure first to ensure the cradle is wide enough to ensure your BEAST will fit.

Here's a quick-reference guide of the base diameters: 

9. WON’T THE COLORED COATING CHIP OFF?

Q: How does the painted coating on the outside hold up? I don’t want to get a colored design and then be disappointed if the color chips off...  

A: The colored coating will NEVER chip off! But how is that possible? Well, because it’s not actually paint: The colored finish on your BEAST is in fact powder coating. Each colored tumbler undergoes this special powder-coating process, which was first developed as an industrial treatment to toughen metals and weatherproof them for outdoor exposure.

This results in each BEAST having a food-safe, scratch-proof, smooth coat of armor.

The color is literally electrostatically applied and cured onto the steel with a UV light. “Tough” doesn’t even come close to describing how durable the finish of your BEAST really is!

8. WHAT HAPPENS IF I DROP IT?

Q: Is the BEAST really as sturdy as it looks? I’m so worried I’ll break it if I drop it!  

A: The BEAST is tough as nails! The cup itself is created with seamless, super strong 18/8 stainless steel. The outside is then powder coated for a diamond-hard finish on the colored designs, or electropolished for a scratch-free surface on the classic stainless steel model. 

This narrow base was developed to fit in all sorts of standard cup holders for ultimate portability, so you can enjoy your coffee in the car, on the boat and even while in a recliner watching a movie! 

Of course, if your car’s cup holder isn’t a standard size, give it a quick measure first to ensure the cradle is wide enough to ensure your BEAST will fit.

7. HOW DOES THE LIFETIME GUARANTEE WORK?

Q: I’m pretty adventurous and my travel tumbler comes with me everywhere. Does this cup really have a lifetime warranty? I’m planning on putting it through its paces…  

A: What you see is what you get with our Lifetime Guarantee! Go wild with your BEAST- it’ll keep up, we promise. But, if you do happen to be especially tough on your tumbler and disaster strikes, don’t worry- it’s covered by a Lifetime Warranty.

Simply fill out the form (it literally takes 15 seconds) to register your warranty so we’ve got you covered in case you ever need to replace a damaged tumbler or lid. Then just reach out to us and we’ll have a new one sent out to you, free of charge!

6. WILL IT LEACH HEAVY METALS INTO MY DRINK?

Q: I read an article that said most metal cups leach lead into your drink. It claimed that there’s only one brand of drinkware on the market that doesn’t do this. What’s the deal? 

A: What you see is what you get with our Lifetime Guarantee! Go wild with your BEAST- it’ll keep up, we promise. But, if you do happen to be especially tough on your tumbler and disaster strikes, don’t worry- it’s covered by a Lifetime Warranty.

“I assumed there was no lead, but since you asked I got curious and bought a lead test kit. Rubbed it all over the inside of my BEAST and the straws... NO LEAD!

Sounds like someone at that other company is trying to boost sales by spreading false information about their competitors!”

5. ARE THE BIGGER SIZES STILL EASY TO HOLD & CARRY?

Q: Some mornings need more coffee than others, if you know what I mean! But are the bigger-sized BEASTS still easy to drink out of, even with their shape and extra weight?    

A: You betcha! They’re ergonomically designed to be super comfortable too - The large 30oz BEAST and the Jumbo 40oz BEAST were both engineered with features to offset the additional weight from that XXL morning brew you love.

Their tapered bases conveniently curve outward, forming a perfect ledge for your hand to rest the weight of the cup’s wider top on.

The non-slip powder coating helps you keep a solid grip, plus there’s also an ergonomic handle you can attach to your 20oz or 30oz BEAST for added functionality.

Pro Tip: For those with limited mobility or seniors, a handle is a great add-on for added stability. The finger grooves and thumb rest provide maximum grip for easy sipping!

4. CAN I PERSONALIZE MY BEAST WITH ENGRAVING?

Q: Can these be laser engraved like similar powder-coated products?  

A: Yes- We offer customized laser engraving for all of our products. If your team, organization, school, non-profit, or business would like to get your own design on some BEASTs, reach out to our Wholesale Team to inquire about our laser engraving. We offer customization for wholesale orders of over 25 items. 

3. HOW SPILL-PROOF IS THE BEAST?

Q: How spill and leak proof is this cup? Will my drink stay inside if I toss it in my backpack?

A: The BEAST Tumblers are spill-proof, but they are not leak-proof.

This means that if for example your driving over a bumpy road, the liquid in your BEAST won't spill out. However, you can't throw your BEAST into your bag; it will leak everywhere.

While the BEAST does have an airtight, vacuum-sealed lid that makes it splash-proof, we can only guarantee that your drink won’t splash out or spill over when it’s being transported in an upright position.

2. CAN I QUIET THE STRAW AND STOP IT FROM MAKING NOISE?

Q: Is there a way to keep the straw from rattling around? I use my BEAST in a quiet office and sometimes the straw clatters around, making a racket when I pick up my cup to take a sip.   

A: Absolutely! If you’ve got one of our newer BEAST models with the updated lid that flips closed, you could try adding some silicone bumpers that slide down onto the straw. These will act as a silencer to dampen any noise from the metal straw clattering against the sides of the sip opening so you can keep your office a haven of silent zen!

Alternatively, if your BEAST has one of our earlier designs with the sliding mechanism to close, try popping the straw through the sip opening and then pushing the slide closure piece forward to hold it taught.

The non-slip powder coating helps you keep a solid grip, plus there’s also an ergonomic handle you can attach to your 20oz or 30oz BEAST for added functionality.

1. CAN I DEEP CLEAN THE SLIDING LID MECHANISM?

Q: Can the sliding sip mechanism on the lid be disassembled for washing? My milky tea gets inside and it’s starting to get crusty and flaky… 

A:  You sure can! The slider on the lid is actually detachable and can be taken off easily for cleaning.

Use something blunt like a butter knife to take off the slider -  simply push it up from underneath, and it’ll pop right off.

It can then be pushed back on again easily once you’ve given it a thorough clean in the sink or your dishwasher.

While these are just some of the questions customers ask about the BEAST, we’re always happy to help answer your must-know details that aren’t covered here, so don’t be afraid to reach out!  

Although I’m a little biased, I think getting the perfect travel tumbler for you is a big decision. It’s going to accompany you everywhere you go, after all!  

I know the BEAST will cover all your bases, now and for a lifetime of adventures to come. Still not sure? Just ask! :)
