No metal taste. The cup rims are smooth and provide a good feel in hand and on the lip. Enjoyed this first in Joshua Tree where it also kept our favorite wine cool in the heat. Completely dripless and spill proof. And the magnetic cups are pretty slick. Birthday gift for my husband to take on our canoe trips but this will go everywhere. He loved it. Ordering more for gifts.

The flask and tumblers are beautiful and simply elegant to use. The strong magnet adds the need for careful planning when I pack my bag or pack to ensure no electronic devices are in the vicinity it’s of the flask…. Adding a bit of complexity. But besides that I am thoroughly enjoying this beautiful set.

Exactly what I needed for travel. With the Pandemic easing up I’m anxious to travel and get out of being confined to my apartment. I traveled with a friend to Atlantic City for a couple of days. Filled my Flask with Margaritas which I refrigerated overnite and we drank a Margarita when we settled in our room at the Borgata. We traveled for a total of 6 hours, 3 hours travel time not including 1 1/2 hours we stopped to eat lunch another 1/2 hour shop for snacks to bring, and we also stopped for Shakes at McDonalds. By the time we checked in at the Reception Desk and arrived in our room we waited for our luggage to arrive it was quite some time. I had the Flask packed away in my luggage. When the luggage arrived we celebrated using the convenient Magnetic Tumblers attached to the Flask and drank 2 ice cold Margaritas. I never added any ice to the flask for fear of diluting the Margaritas they continued to remain cold for a number of hours no ice needed it was worth the purchase. Easily washed warm water and soap packed away for my next trip. Thank you food52
