Sertodo 16oz Pure Copper Cup | Hand-Hammered, Heavy-Gauge Copper Cups for Water, Cocktails & Moscow Mules | 100% Solid Drinking Tumbler

Love this!! Trying to get away from plastic while I drink my daily water! Super happy with quality! A bit pricy, but worth it!

Very high quality and excellent weight and craftmanship. I'm very impressed and like it, the size is perfect. Great job!

Beautiful 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

Nice big cup. Beautiful and quality made

Tarnished after 1 use. Disappointing. Otherwise decent cup thus far.

I thought this copper cup,would be perfect but the minute I poured water in it dark spots appeared on the interior. I tried copper polish to get rid of them but they didn’t really go away. I’ve never had a copper vessel do that before.

Besides loving to drink the tasty, cold water from this 25oz cup, I'm impressed with the beautiful, gleaming, hammered extrrior of this uncoated copper cup. The water, drunk from the copper cup, offers many holistic benefits for our bodiesIts the "real thing". I bought one for my sister last week...She's equally impressed!!
