How do I know the cups are solid copper and not coated steel?

Two ways. First, a check you run yourself: pure copper is non-magnetic, so a fridge magnet won't cling to a real copper cup the way it grabs a steel core — try it the day they arrive. Second, on our side: every production batch is sent to an independent lab that verifies the copper is genuinely pure, with no lining and no nickel.

Are these good for Moscow mules, or just water?

Both. The cups are a classic for a Moscow mule — copper keeps it ice-cold — and they're just as good for the traditional copper-water ritual or an everyday glass of water. As with any solid copper cup, enjoy acidic drinks like a mule freshly made and rinse the cup afterward, rather than letting them sit for hours.

Do they really keep drinks cold?

Yes — copper conducts heat quickly, so it pulls warmth away from a cold drink and you'll often see condensation bead on the outside within minutes. It's why copper cups feel so cold in the hand. They're not double-walled insulated tumblers, though — the cold you feel is the copper itself doing the work.

The cups are changing color — are they defective?

No — that's natural patina, and it's normal for solid copper. The color deepens over time; some people love the antique look, others keep it bright. A cut lemon dipped in salt restores the shine in about a minute — then rinse and dry.

How do I clean them — are they dishwasher safe?

Hand-wash only. The dishwasher is hard on copper's finish and will dull or spot it. Rinse with warm water after use; for shine, rub gently with lemon and salt, then rinse and dry. Skip abrasive pads and harsh chemicals.

Do they come as a pair, and do they make a good gift?

Yes — it's a set of two, which is exactly why people gift them: two of something real and lasting instead of one disposable thing. They arrive ready to give, and the lifetime craftsmanship guarantee travels with them.

The 5-second authenticity test

Is your copper real? Most aren’t.

A meaningful share of the “pure copper” cups sold online are steel — spun cheap, then painted or plated to read as the real thing in a photo. Hold a magnet to the base. If it clings, there’s steel under that finish.

One honest caveat the hype merchants won’t give you: the magnet is a screen, not a lab. That’s exactly why we don’t stop there.

Say no to plastic

Break free from microplastics.

Choose pure water.

Every plastic bottle sheds tiny particles into what you drink, day after day. Copper doesn’t. Switch to a vessel people have trusted for thousands of years — one you rinse, refill, and never throw away.

Heritage, not hype

Why people have trusted copper for thousands of years

Copper is naturally antimicrobial — an effect scientists call the oligodynamic action, a documented property of the metal itself. Long before it had a name, Ayurvedic tradition stored water in copper overnight and drank it in the morning, a ritual known as Tamra Jal.

We don’t make medical claims — but the heritage, and the metal, are real.

Read the science

Proof, not promises

Lab-tested for purity. Provable in your own kitchen.

Talk is cheap, so we don’t ask you to take our word for it. We pull a sample from each batch and have an independent lab verify its purity: 99.9% solid copper, with no inner lining, no nickel, and no plating. Then we put a magnet in the box so you can confirm it the day it lands.

Magnets that stick

The magnet test — do it on any copper

1
Hold a small magnet against the bottom or side of the cups.
2
Pure copper is non-magnetic, so the magnet won’t cling to it.
3
If the magnet grabs and holds, there’s magnetic steel under that finish — it is not solid copper.

A free magnet ships in every box, so you can screen Coppora — and any other “copper” piece in your cupboard — the day it arrives.

Why it’s different

Why people choose Coppora

Lab-verified pure copper — not “copper-colored.”

We have an independent lab verify each batch’s purity — confirmed at 99.9% solid copper. Most “copper” cups are never tested at all.

Passes the magnet test — and proven beyond it.

Pure copper is non-magnetic, so we put a magnet in every box to screen ours — and any other “copper” piece. Beyond the magnet, every batch is independently lab-tested.

Hand-hammered from single copper sheets.

No lining, no nickel core, no glued seam, no coating to flake into your water. One artisan, thousands of hammer marks — every cup slightly different.

Made to be the last cups you buy.

Copper doesn’t crack or shed microplastics. Rinse, refill, hand them down — backed by a lifetime guarantee, not a 12-month warranty.

A plastic-free daily ritual.

Fill them at night, drink in the morning — tamra jal, a habit kept for thousands of years.

A living finish that earns its patina.

Real copper deepens to a warm patina over time — the surest sign it isn’t coated steel. Prefer the mirror shine? A minute with lemon and salt brings it right back.

Do it yourself

The 5-second magnet test

Hold a small magnet to the bottom or side

Pure copper is non-magnetic — it won’t cling

If it grabs and holds, there’s steel under the finish — not solid copper

The magnet is a quick screen, not a lab — some steels are only weakly magnetic. That’s why we don’t stop there: every batch is independently lab-tested for purity, too.
