It’s Monday, 8:45am and you’re queueing for your oat milk latte at your favourite coffee house. In your hand, you’re holding your tactile bru cup, the coffee-lovers response to climate change. Today you’ve chosen Scarlet Heart because passion is your middle name. Everybody hates Mondays, but not you. You’ve got a cheeky glint in your eyes because you know what’s coming….. Someone’s coming over to compliment you on your reusable coffee cup.

Bru - helping you fall in love with Mondays the eco-way 


  • Barista-approved cup height for easy use under commercial espresso machines
  • 340ml capacity which is your regular latte size but also fits smaller drinks like flat whites
  • Double walled insulation keeps drinks hot for up to 3h & cold for up to 6h
  • Outside of the cups always remains a comfortable temperature to touch
  • Matt powder coated for increased durability and quality feel
  • Wide base and bottom-heavy (bootylicious) design for stability
  • Dishwasher-safe, high impact, heat & chemical resistant Tritan® lid 
  • Stainless steel cups are recyclable at end-of-life (contact us for recycling advice)
  • BPA and BPS-free so that you don’t have to worry about any harmful chemicals

Please note this cup is not leak-proof. The lid is designed to allow air pressure to escape, so that your drink flows effortlessly. 

Disposal coffee cups are naff. Noone wants to be seen with single use cups any more so here at bru, we wanted to make reusable coffee cups something of a statement. Over the last few years, we’ve lost sleep in our search for the trendiest colours so that you can be proud to show off your reusable cup whilst protecting the environment from any more unnecessary waste.



Why make the switch to stainless steel cups?         

Environmentally friendly – because the vast majority (around 85%) of stainless steel is made using around 50% scrap metal, this reduces the need to mine for more virgin materials thus, saving water, fuel and protecting local environments from further degradation.

Reusable – functionally, you should be able to use and re-use your bru cup for the rest of your life although aesthetically, your cup may show signs of age. If your friends describe you as “a bit clumsy” then we suggest opting for a darker colour bru cup which will be a lot more forgiving if it gets scratched, stained or dropped.

Recyclable – like all stainless steel, these cups can be recycled without ever losing material quality. Tip: keep a little box in a storage cupboard and fill it with stainless steel items. When this box is full or if you are going to your local Council recycling centre, take the box with you and recycle the contents so they can be melted down and made into something new. Unfortunately, the lid is not currently recyclable (we’re working on that!).

Safe – stainless steel doesn’t leach chemicals and doesn’t react with the liquids you consume. Our lids are also BPA- and BPS- free. Because these cups are so easy to clean, they are the healthiest, most convenient and eco coffee cup choice for everyone who wants to make a positive impact.



We recommend rinsing your bru cup with hot water after every use and washing with hot, soapy water and a brush or sponge within 24h after use. Keep the lid off to allow the cup to dry fully  and keep the inside smelling fresh. The lids can be placed in the top draw of the dishwasher to clean. Occasionally we suggest removing the seal and slider from the lid for a deep clean. All colour cups except Rose Gold Intense can also occasionally be washed in the dishwasher as long as the wash cycle does not exceed 70 °C. Environmentally friendly detergents and sustainable bottle brushes and sponges are always encouraged!

looks good

I love the look of these cups and they keep hot drink hot longer than advertised. The colours are good and bold and the cups fit nicely into my hand.

Fantastic Cup

This cup is fantastic, when I'm busy with work, its so good to be able to have a cup of tea stay hot an hour after I've made it. I've even bought them for friends.

You'll be inseparable from it

Lovely design, cosy to hold in hands, comfortable to drink from, and holds heat really well. I quickly became inseparable from my Bru mug <3


I'm absolutely obsessed with this stylish cup! It is often a conversation starter in many random places, the latest one being my local bank branch ha!
It is a great size - I've switched from my usual chunky chilly bottle -, super light and I've found that its shape means that it is so much easier to clean (saves a lot of time). I'm pretty clumsy so I've already dropped it a few times but you would not be able to tell as the material is very sturdy! Thank you, definitely recommend!!

A brilliant eco alternative to disposable coffee cups!

A compact size for transporting around in my work backpack, easy to clean and has a very stable base. I took this photo before boarding my plane! Nothing like hot coffee for hours before your flight.
