HealthAndYoga™ qCup Pure Copper Tumblers for Drinking - Ayurvedic Health Pure Copper Cups – 2 pcs. set - 250 ml.(8 fl oz) (Plain)

Very nice set of pure copper cups. The outside has some sort of coating, evident from the fact that it doesn't tarnish. The inside will tarnish quickly if exposed to water and air. Tarnish seems to come off somewhat when cleaned with lemon juice. The cups are lightweight.

Gave as gift, happy with quality.

I'm really happy with this product. The quality is great.

This is not cooper at all. They got all tarnished within one used. I bought it for my kids, they only drink filtered water. We used it less than a week and it looks horrible. I tried to clean it with natural products for cooper and nothing worked. It’s probably dangerous to drink out of this. I WANT MY MONEY BACK!!!

I love the fact that these tumblers keep my water ice cold. Extremely easy to clean, they are cute and perfect size for the price. The reason I purchased these tumblers is because Per Google search engine:Drinking from copper cups can improve your digestive health. Copper has been found to kill bacteria that cause inflammation in the gut, possibly improving ulcers, indigestion, and infections. Additionally, copper helps to break down fats and proteins into more digestible forms, which can help with digestion.

I liked the look but not sure why there are black spots on the bottom after use

A small cup, but sturdy. Wish I had bought 2 more. Will definitely buy 2 more with Next purchase

We read about how copper is good to drink from. We have used these everyday, and I think they are the cutest little cups! They’re good size for my toddler or a quick drink of water. It didn’t take long for them to start to tarnish, but not bad. And I’m trying to care for them exactly as the instructions state. They’re easy to clean and worth the buy! These do not come with lids.
