What is the LU-SAINT story?

Founders Harry and Brittany weren’t able to find a reusable coffee cup that was ultra stylish but also good for the planet. Most reusable cups consisted of complicated lids and after a few uses, would let off a bad odour. Harry & Brittany designed the LU-SAINT cup themselves, without compromising form and function, producing a product that flaunts a luxury feel.

What is borosilicate glass and why do you use it?

Borosilicate glass is the cooler, strong sister of standard glass. Light weight, microwave and dishwasher safe, it holds in heat, it’s hygienic and it’s comfortable to use. We believe that glass is the way forward to ensure your coffee also tastes its best, too.


Can the glass cup break?

Yes, although borosilicate glass is said to be stronger than standard glass, your cup may still break if dropped.


How should I clean my LU-SAINT cup?

We recommend handwashing your LU-SAINT cup with a small amount of dishwashing liquid and warm water. In saying this, the glass and silicone components are dishwasher safe. You shouldn’t need to wash the wooden base, but if you do, wipe with a damp cloth - the base is not suitable for the dishwasher.


Why should I stay away from buying a coffee in a throwaway cup?

Between the paper walls of disposable cups lies a film of plastic. This plastic could contain harmful chemicals and sadly, most plastic in the world isn’t recycled, but usually dumped in our landfills. If you buy 5 takeaway coffees a week and replace your disposable cup with a LU-SAINT cup, you’ll be reducing the number of throwaway cups by 240 per year. That’s 240 less cups making it to our landfills – it adds up.


Wait, I thought silicone was plastic?

Nope. Silicone and plastic don’t share the same ingredients and are completely different in terms of sustainability. Silicone is actually an elastomer, meaning its manufacturing processes are far more eco-friendly.


Will coffee stain the silicone?

Surface stains may be evident however they are easily removed with baking soda (bi carbonate soda), or a damp cloth and a small amount of dishwashing liquid. We chose silicone for this reason, rather than plastic. Plastic can stain and hold bad odors forever.


Can I put my LU-SAINT cup in the microwave?

Yes, the silicone and glass are microwave safe. However, we wouldn’t recommend putting the wooden base in the microwave.
