Review: Quality Flask - Love it. Great size. Keeps beverage cold or hot. Like the way it looks. Durable. Would buy it again.
Review: I love this cup - I absolutely adore this Tumblr. I love the color and how it changes throughout the cup. I love that my drinks actually stay cold, if I fill it up with ice water around midnight when I wake up around 9:00 a.m. the ice is still there. It keeps drinks cold longer. The one lid that you do have is actually spill proof. It's super easy to clean, it's super easy to use and it just kind of fits in your hand. I can easily take this to work with me if it's right in my bag and in my cup holder

*by C***M on January 1, 2026*

These Iron Flask tumblers are all great quality and really beautiful. They keep water hot for hours (5 hours and counting). Love them! Well made. Nice rubber bottom to not damage the wood table. Wish the price were a bit less but I do love them in general.
