Copper Cups - 12 Oz set of 4 - A Unique Way To Enjoy Wine - The Perfect Pure Copper Tumbler for Water - Copper Drinking Cups Better Than Glasses or Plastic - Moscow Mule Copper Cup For Drinking

I just received these today, and they are beautiful. I cannot speak to tarnishing, but they definitely are 12 oz cups, though they appear to be smaller, probably due to the style. How to measure? Fill it to the top and pour into a marked measuring cup. Twelve ounces. I bought them for the bathroom. Tomorrow, I shall receive the matching pitcher. My plan is to keep the pitcher, filled with water, on the table with two of the "glasses" to drink throughout the day.

We bought these cups for outdoor dining - we needed something unbreakable but wanted to avoid plastic. We are very happy with the purchase. There cups are beautiful, elegant and have a lovely weight in your hand. We've experienced some very mild tarnishing on the interior on some cups since we started using them (they arrived about 3 weeks ago), but this is to be expected and is not in any way objectionable. The exterior has maintained it copper shine beautifully (we do expect some patina to develop over time as is normal with copper). We hand wash them with regular dish soap.

Perfect size for the bathroom and very easy to clean.

Good

Tarnished and green/brown within 1 day. We have purchased this and the travel tumbler and this product turned green and brown after one use while my bottle has never had this issue. Not sure what the difference is but would not recommend, even though it's part of the process I feel it should take longer than a day to turn colors.

They seem like OK quality but they are definitely only 8oz. Returned due to false advertising.

I look nice and are great for kids because they won't break however, they do scratch very easily. I try using only soft side of dishwashing sponge but the bottom of the inside of the cup still gets a few scratches.

Delivery was faster than expected, and it impressed me that Kosdeg included a warranty card which you can fill out online. My interest in copper lies more in the potential health benefits of storing water in copper, but holy cow these cups are just plain beautiful! And I could hardly believe the claim that they were 12-ounce capacity until I tested it out myself. My 4' 11" mother with proportionately small hands can easily hold these cups! Whoever designed them evidently put a lot of thought and trial into their design. When you pour room-temperature water into them the cups become cold as if refrigerated. I know it's an illusion, but it's a cool one! (Pun intended.) I would like to dispense with glass and fill my whole cabinet with these copper beauties!

Part of my health ritual. Just looking at the lovely copper cups and covered copper water filled jug reminds me every day to drink my mineral infused water quota for the day.

A lovely design of pure copper. Fits nicely in hand, washes easily. Have used for water, wine, and juice.

Ein Traum, habe diese Becher bzw Tassen bestellt um bruchsichere Getränkegläser für unseren Poolbereich zu haben. Heute traf die Lieferung nach kurzer Wartezeit ein. Eigentlich sind diese Becher zu schade um sie nur am Poolbereich zu verwenden. Sie wirklich wunderschön

飲み物が飲みやすいだけでなく 安心素材でとても満足しています。

Very nice quality!
