A solid copper bottle you can check yourself, with a fridge magnet.
950ml, hand-hammered, unlined inside. Most copper-coloured bottles are plated steel. A fridge magnet catches them in four seconds. If one grips ours, keep it. We refund you.

- 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.
Is wanting a copper bottle a bit silly?
Fair question. Most of what gets said about copper bottles online is wellness talk, and a lot of it would not survive a second look. If that has put you off, you are not wrong.
So we will not add to it. This page makes no claim about what copper does for your body. It is a bottle.
What is left is simple. It is a heavy, hand-hammered thing that looks good on a desk, it replaces the bottle you already carry, and it is made of the metal it says it is. The rest of this page is about how you can check that last part yourself.
“Sounds like pseudoscience bs.”
Top comment on a public Reddit thread about copper bottles. Plenty of the claims are. We do not make them.
Will it poison me?
Used with plain water, no. Copper in drinking water has a published Australian limit, and the table shows it.
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.
| Reference | Copper in water | What it means |
|---|---|---|
| NHMRC health guideline | 2 mg/L | Should not be exceeded |
| 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.
If you find a coating inside yours, email us a photo and we refund you.
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.
Plain water, emptied and refilled, is the fix. If fresh plain water still tastes wrong to you, send it back inside 60 days and we refund it.
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.
