FAQ – OneCup Official


If I break my cup do you replace it for free? 

No. We don't offer refunds or free replacements for broke cups. However, you can purchase just the glass on our website, as an accessory. 


What are the cups made from? 

The cups are made from Borosilicate Glass and Silicone Rubber. 

What's so good about Borosilicate Glass?

Borosilicate Glass is said to be stronger and lighter than ordinary glass. It is resistant to temperature changes. It is a very strong glass composition that will not cloud or stain from use. It is most definitely dishwasher safe.

That said, Borosilicate Glass is still glass and it will break if dropped or handled incorrectly. So take care!

What's good about Silicone Rubber?

The silicone rubber offers a beautiful ergonomic feel, non-slip grip and cool touch coating. The silicone rubber pieces of the cup are again, fully dishwasher safe.

Where are the cups manufactured?

Our products are manufactured in China. We work with Chinese factories that meet and operate under the same social responsibility guidelines as our ethics.

We choose to work with Chinese companies as they produce high-quality products in a timely manner which are very reasonably priced. In turn, we are able to offer you our incredible earth-saving products at an affordable price so we all can make a greater impact. 

So, what about plastic? 

We designed all our products to not contain any plastic.

Do the lids seal completely?

No. None of our lids seal completely. We designed our cups to be enjoyed on the go.

The OneCup Lid;

  • does NOT have screw threads or grooves that are hard to reach or clean
  • is ONE simple component
  • is simple to use, to put on and take off
  • is incredibly easy to clean


Do you replace stained lids?

No, unfortunately we don’t.

Can I mix and match the colour of the lid and sleeve?

Not at this time. We sell the cups as a full-colour set (both lid and sleeve are the same colour).

Can I order extra lids or bases (apart from what is included with the cup?)

Not at this time. 

What are the dimensions of the Stainless Steel Straw?

The stainless steel straw is 250 mm high and 11 mm in diameter. We designed it this way for thicker drinks and bubble tea pearls. 


Are there different sized/styles of the straws available? 

Not at this time. 

How do you clean the cups? 

We suggest you pick up a bottle brush cleaner to clean all the way to the bottom of our cup.  Any bottle brush cleaner will do fine!

Your OneCup are completely dishwasher safe. They are easy to clean with no need to remove the silicones, and we suggest leaving the lids the correct way, no need to reverse.

Can you put the cups in the microwave? 

While we don't encourage the use of microwaves for health reasons however you can put your cup in the microwave without the steel straw.

Is there a Premium Drawstring Bag included in every cup? 


What is the Premium Drawstring Bag made from?

It is a dual-walled, cotton fabric bag and it's designed to absorb the last dribble. This bag does not have a plastic inner to make it waterproof. 

But won't the bag get stained?

Yes. It's designed specifically to carry your cup and absorb the last dribble of your beverage. Over time this will cause staining if not washed or treated properly. We designed this bag for this reason and we hope to see lots of stains on your Premium Drawstring Bag and not in your personal carry bags! 

Is the bag machine washable? 


Is the packaging recyclable?

Yes, our packaging is recyclable. We encourage you to reuse the box for storage however you can simply recycle your box where you would normally recycle cardboard.

Do you accept returns? 

We only accept returns on damaged or defective items.

Do you accept returns for a refund?

No. If you did receive a damaged item, it will be replaced with a new item.
