Question 1

Is it safe to drink from copper every day?

Accepted Answer

Our glasses are food-grade, 100% pure copper and third-party lab tested by SGS. Use them for plain water at room temperature, the way copper vessels have been used for generations. If you have a health condition, check with your doctor first.

Question 2

Why plain water only?

Accepted Answer

Copper reacts with acid. Lemon water, juice, coffee, tea and other acidic drinks can draw copper into the drink and mark the finish, so keep those in a regular glass.

Question 3

How long should water sit in the glass?

Accepted Answer

About three hours. Many people fill it at night and drink it first thing in the morning.

Question 4

What are the dark spots that show up over time?

Accepted Answer

That is patina, normal oxidation on real copper, and a sign the glass is not plated. Salt and lemon, white vinegar, a cut lemon or a little ketchup takes it off in about a minute.

Question 5

Can it go in the dishwasher?

Accepted Answer

No. High heat and harsh detergent damage the matte finish. Wash by hand, rinse well and dry right away with a soft cloth.

Question 6

How do I know it is pure copper?

Accepted Answer

Hold a magnet to it. Steel and plated cups pull toward a magnet, and pure copper does not. Each glass also weighs about 120–130 g, heavier than a typical 80 g market glass.

Question 7

Do I need an account to order?

Accepted Answer

No. You can check out as a guest. An account just lets you see your orders and tracking in one place, and you sign in with a one-time code, never a password.

Question 8

How do I track my order?

Accepted Answer

Your tracking number shows on the thank-you page right after you pay and in your confirmation email. If you have an account, it also shows on your account page.

Question 9

What is your return policy?

Accepted Answer

You have 30 days from delivery to return your glasses. Sign in to your account, choose the order and press Start a return; we email you a free prepaid label. As soon as your return is delivered to us, your refund is issued immediately.
