Stay hot for hours.
I work in a hospital, and find it great that I can take my time to drink it.
This cup is so practical, I love that it doesn’t leak. It’s perfect for a busy mum on the go. The colours are so aesthetic, I’m honestly obsessed.
I’ll be taking this cup everywhere with me, love that I can throw in my handbag in the morning and it doesn’t spill a drop. No leaks at all, it’s amazing! Super easy to drink from and cute colours, will be buying more for Xmas presents I think! Highly recommend these cups.
I’m very happy with Kalu and my coffee cup. I had a small problem with my cup and I contacted them and they replaced very quick, also they are very friendly. Highly recommended.
I loved mine so much I came back for another one and one for a friend. The only thing that I would change is to make the cup a bit bigger as the clever lid design reduces the amount that you can put in it, so I would love to see a larger one. Still the absolute best grab and go cup ever made.
Absolutely perfect. I have been looking for a non metallic cup for ages so was very pleased to find this one. Spill proof also. I'm delighted with this cup.
This product does exactly what it says. Keeps my green tea wonderfully hot all day. Doesn't spill, looks lovely and not hot to hold. Love how easy it is to open by just pressing the button and best thing easy to drink from without dribbling as my other coffee cups have.
Bought two one for myself and my husband

Absolutely love
Gorgeous colours, but unfortunately unable to use these as they are gifts.
Awesome cup
Love my new Kalu cup. Great product, perfect shape and size that fits in my cup holder. No spills to worry about and definitely holds the heat for hours. Thanks, so happy with my purchase.
Love my Kalu. Easy to use one-handed and keeps my drink hot all day. Doesn't leak so I can pop it in my bag and clean it at home without worrying it'll make a mess.
Great cup, it is what it says.
Super love my Kalu cup! I don't have to reheat my coffee again! It's also spill proof - so perfect if you have little kids around. Plus I super love the color! It's my favorite cup so far!
Does exactly what I want and looks lovely
Great product
Very happy with my purchases. Easy to clean, keeps drinks piping hot or cold for a very long time. Highly recommend.
Really impressed. When the lid is sealed NOTHING leaks. It keeps my coffee/tea nice and hot and it looks fab. Very happy and will be ordering one for my hubby soon 😄
It’s my new fave tumbler! Aside from looking aesthetic, my coffee really stayed warm for hours without the metallic taste like the other usual tumblers. Plus, no spills even if I put in my bag. It’s also so easy to clean.

FAQ's
Is the KALU Cup leak-proof?
The lid is designed to seal when fully closed and assembled correctly. Make sure the silicone ring sits flush, twist both lid pieces together tightly and close the button lid fully. Before putting the cup in a bag, turn it upside down to check the seal.
Can I use it for hot and cold drinks?
Yes. The double-wall stainless steel body has a copper-lined insulation layer to help keep hot drinks hot and cold drinks cold. Briefly vent hot drinks before sealing. If the button feels stiff, wait and open slowly.
What is the cup made from?
The 350 ml cup has an 18/8 (304) stainless steel body, copper-lined insulation and a ceramic interior. It is BPA-free and lead-free.
How do I clean it?
Hand wash the cup and both parts of the lid, then rinse and let them air dry separately. Remove the silicone ring weekly to clean the groove. Do not use a dishwasher, microwave, freezer or abrasive sponges.
Why ceramic interior? What's the difference?
Stainless steel interiors can affect taste over time. Ceramic doesn't interact with your drink — no metallic taste, no absorbed odours, easier to keep clean.
Are the materials safe?
The cup is made with 18/8 (304) stainless steel and a ceramic interior. It is BPA-free and lead-free.
How does it stay hot (or cold) for so long?
Double-wall insulation with a copper lining between the walls. Copper reflects heat back into the drink.
