- Grab any fridge magnet. Copper is not magnetic. If a magnet grips it, there is steel under the colour. Keep the bottle and we refund you.
- Unlined inside. Your water sits against copper, not a coating. Look inside the day it arrives and check.
- It will darken with use. Bare copper does that. A bottle that stays shiny forever has something sealed over the metal.
What customers of our first store said
Heavier and nicer than I expected
"Bought it after seeing the ad and wasn't sure what to expect. It's solid, the hammered finish looks better in person, and it doesn't feel cheap at all. I fill it at night and drink it first thing. The water tastes a bit softer, if that makes sense. Already had two people at work ask where I got it."

"Great bottle. It started going darker after about two weeks, which freaked me out [...] Lemon and salt brings it straight back. I'm taking off one star only because I wish I'd known that up front. Otherwise really happy."

"Got this as a birthday present for my mum, who's big on Ayurveda. She loved the box and it arrived quickly. She uses it every morning. I've since ordered one for myself."
Photo: King's CopperKimReplaced my plastic bottle for good
"I was trying to get rid of plastic, and this has done it. It sits on my desk all day. It doesn't sweat like my steel one did, and it's become a bit of a ritual. It's worth the price."

"Beautiful bottle and it feels really solid. It's heavier than a normal drink bottle, so it's not my gym one, but it lives on my desk and I use it every day."

Why Copper?
~ According to Ayurveda, water stored in copper overnight is believed to cleanse and support the stomach. Copper is also thought to stimulate natural digestive movements, promoting smoother and more comfortable digestion.
~ Copper has a natural contact-killing effect on harmful bacteria including E. coli, Vibrio cholerae, and Shigella flexneri. Water stored in a copper vessel for 6–8 hours is naturally purified - no filters, no chemicals required.
~ Copper is an essential trace mineral that supports red blood cell production, healthy iron metabolism and overall cellular function.
~ Copper plays an essential role in energy production, connective tissue health, and cellular communication.
~ In Ayurveda, drinking copper water first thing in the morning is a centuries-old ritual believed to help the body reset, refresh, and recharge.
The Research Is There
~ Copper plays an essential role in maintaining strong bones and healthy connective tissues. It is also believed to have anti-inflammatory properties that may help support joint health and ease arthritis-related discomfort.
Will it poison me?
Copper plays an essential role in the body, supporting wound healing, healthy cell production and connective tissue health. While it may also contribute to joint health, excessive copper intake can cause harmful side effects.
Two things push copper into water faster: acidic drinks, and water left standing for days. Both are yours to control. Plain water only, and empty it rather than leaving it for days.
The rules, all four of them
- Plain water only. No juice, cordial, lemon, tea or anything fizzy. Acid draws copper out fast.
- Do not leave water standing for days. Fill it, drink it, refill it.
- Never the dishwasher. Warm water and a bottle brush.
- Dry it upside down with the lid off.

| NHMRC aesthetic guideline | 1 mg/L | Above this it can affect taste |
Figures are from the NHMRC Australian Drinking Water Guidelines. They describe drinking water generally, not this bottle.
Is it lined inside?
No. The inside is bare copper, with no liner and no lacquer. Your water sits against the metal.
That is the whole point of a copper bottle. A coated interior means your water touches the coating, not the copper. You do not have to take our word for it: look inside the day it arrives. Bare copper looks like the outside, the same warm colour and the same hammer marks. A lacquered interior looks glassy and faintly yellow.
Will it make my water taste metallic?
Fresh plain water should not. When people get a coin taste, it is nearly always one of two things: something acidic went in, or water sat in it for days.
Drinking from copper containers is generally safe. However, limiting consumption to two to three times a day is recommended to help avoid side effects such as stomach cramps and vomiting.
Most copper bottles online are not copper.
Forming a bottle from solid copper takes a lot of copper, and copper is expensive. Electroplating a thin copper skin onto a cheap steel tube costs a fraction of that, and it looks the same in a photo.
But thin plating tarnishes, and tarnish gives it away. So the inside gets sealed with a clear lacquer. That layer keeps the bottle looking new forever, and it means the copper never touches your water.
So a copper bottle that still looks brand new after months is not a good sign. It is the tell. You may already own one and have no way of knowing. The tests below take a few minutes, and you can run them on any bottle, including ours.
The word is not the metal.
Think laminate on a flat-pack shelf. It looks like timber until the day it peels.
Four ways to check any copper bottle at home.
Hold any fridge magnet to the body. Copper is not magnetic. If it grips, there is steel under the colour. This catches the most common fake.
Copper is dense. This one is about 250g empty. A plated tube the same size feels light and rings when you tap it. This catches fakes a magnet misses.
A dab on the outside brightens bare copper within a minute. On a lacquered surface nothing happens.
Real copper darkens within weeks. A bottle that still looks brand new in six months was sealed at the factory.
If a magnet grips it, keep it. We refund you.
That is the guarantee, word for word. Test it the day it arrives. If a magnet grips the bottle, email us a photo. You keep the bottle and we refund your order. If you bought more than one, keep all of them.
We do not include a magnet. You already own one. Use your own, so you know it is not ours.
It will go dark. That is the receipt.
Bare copper reacts with air and water. Within weeks it dulls, goes a deeper brown, and can go faintly green where water sits. That is what real copper does.
A plated bottle sealed under clear lacquer cannot change colour, which is why the fakes stay shiny forever. So when yours darkens, nothing has gone wrong. It is showing you what it is made of.
First use: wash it with warm water, fill it with plain water and use it. Overnight: fill it at night and drink it the next day. Then empty it and refill. Do not leave water sitting in it for days. Cleaning: warm water and a bottle brush, then dry it upside down with the lid off. Half a lemon and a spoon of salt on the outside brings the shine back in about a minute, then rinse. Or leave it dark. Both are fine.
Not dishwasher safe. Detergent leaves it blotchy. Nothing acidic inside. No juice, lemon water, cordial, tea or anything fizzy.
If you want a bottle that looks the same in year three, buy stainless steel. We mean that.
Care is thirty seconds: empty it, rinse it, dry it upside down.

Everything else people ask
Do you send a magnet in the box?
No. Use any fridge magnet you already own. That way the test does not depend on anything we supplied.
What if the magnet grips it?
Then it is not what we sold you. Email us a photo of the magnet on the bottle. Keep the bottle and we refund your order. If you ordered more than one, keep all of them.
Mine has gone green inside. Have I ruined it?
No. Copper left wet goes faintly green where water sits. Half a lemon and a spoon of salt with a soft cloth, then rinse well. To stop it coming back, empty it and dry it upside down with the lid off.
Can I put anything other than water in it?
No. Plain water only. Juice, lemon water, cordial, tea and fizzy drinks are acidic and draw copper out fast.
Can it go in the dishwasher?
No. Detergent strips the surface and leaves it blotchy. Warm water and a bottle brush.
Will it leak in my bag? Does it keep water cold?
The cap screws onto a silicone washer. It is a single-wall bottle, not insulated, so cold water comes to room temperature within a few hours.
I have never heard of this brand.
That is fair. It is why the page gives you a test you can run on the bottle yourself instead of asking you to trust the name.
Do I need an account to buy?
No. Checkout works as a guest.
