Sertodo 25oz Pure Copper Cup | Hand-Hammered, Heavy-Gauge Copper Cups for Water, Cocktails & Moscow Mules | 100% Solid Drinking Tumbler

This is the best copper cup I've ever purchased, the quality of the cup, is incredible, everytime you hold it in your hand it feels like no other. The only problem I have is that, it doesn't come in a larger size, I have to refill it multiple times at one setting

Lovely. Great for self or as gift. Genuine copper.

Good quality.

I would like to give it 3 1/2 stars just because I ordered two different brands of copper cups and the other ones are superior in every way these are a decent thickness, solid copper. I’ve been using them for one day now and I’m noticing black spot starting to form from water being on them very quickly and it’s not easy to take off if you can imagine inside the cup without chemicals and or abrasive sponges, etc. The other brand I purchased are smaller, but they’re thicker heavier duty, and feel solid in your hand. I’ve been using them for about a month now and no black spots. Water spots come off easily with a microfiber towel and I can’t tell if any tarnishing whatsoever or water spots. I’m not sure if it’s a different grade of copper but for the price I’m not understanding why these are tarnishing so fast compared to these others which haven’t shown any signs of tarnishing. The third picture is a prince of Scott’s glass that I bought and have been using for a month straight I did not get any free products for this review. I paid for them myself. I don’t mean to compare the two brands but the other ones are superior. I’ve only wiped them with a microfiber towel. Well, the larger ones I’ve used brushes, mild soap, and I really don’t want to use a metal polish, but it seems like it’s gonna be the only way I can get these to stay consistently clean

I have been looking for a pure copper, larger cup that's simple, beautiful and affordable. This one is a work of art, and I'm so happy to have found the Sertodo copper company. The video was impressive, and the cup was Perfect, packed very well and arrived quickly. I read that 85% of people in this country have a copper deficiency, which makes this purchase a healthy one. Get one (or 10) .....you will love it! ♥

This I returned. Cup started turning almost immediately.

Perfect size especially for children. Health benefits are great for copper. Cleaning is easy - salt on a lemmon and rub it - one cup takes about one minute to bring back the shine. Highly recommend.

I was very disappointed. It started rusting in the bottom.
