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. Read more
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 Read more
IronFlask makes the most high quality, prettiest and durable water bottles! I use this one at home next to my working computer and it makes it so convenient and easy to stay hydrated during the day. I generally like drinking cold water and this bottle does a great job to maintaining it cold for the entire day even the day after even WITHOUT ice! Finally, I look forward for bottles without small hinges or gaps that makes it a pain to clean, and this one is perfect with its simple and clean design. 100% recommended! Read more
This 24-ounce tumbler is the perfect size, and the color is amazing! It keeps ice cubes from melting for hours, and always keeps my water cold. Iron Flask products are durable and well-made. I already purchased another one! Read more
After over a year of daily use, I can say that this is *almost* the perfect tumbler. No leaks, no sweating, fits every cupholder I’ve encountered, and it keeps beverages cold for many hours. I go to bed with ice water and it’s still full of ice in the morning. My only complaint is that the lid can often be very difficult to open. Read more
I received my 32 oz. "Dark Rainbow" (pretty!) IRON °FLASK tumbler yesterday and feel compelled to write this review to encourage you to get your own NOW! I live in the sultry south where heat and humidity will turn your ice-filled glass into a watery drink within minutes. Initially, I bought this to use as sort of an "individual" ice bucket so I could refill the ice in my glass of tea without getting up every five minutes of a Prime-binge, especially any compelling thriller. Indeed, for the first night of having this beauty, that is precisely how I used it—and it worked perfectly. At the end of the night, I left ONE lone ice cube in the tumbler to see how it would fare. Twelve hours later, that solitary ice cube is only partially melted and still icy cold! The tumbler itself comes with two straws, and two lids: one for use with a straw and one flip-top for use with hot drinks (or if you just prefer to drink directly from the tumbler). Each top is very thick—I've never had a tumbler where the top is designed to also provide insulation. All-in-all, I am very impressed with the quality and functionality of this tumbler. I only write reviews when I am deeply disappointed with a product to serve as a buyer-beware herald, or am over-the-moon pleased and what to provide fellow shoppers to confidently purchase. Happily, this tumbler is the latter. I haven't tried it in my car's cupholder as yet, but believe it will easily fit there as well. Also, there was ZERO condensation when the cup was filled to the brim with ice and none when I checked that solo melting ice cube this afternoon. I love that I can place the cup on any surface without worrying about damage to the finish. NOTE TO MANUFACTURER: I still would like to find a mini-ice bucket (48-50 oz. would be ideal, and not more than 5" diameter) to use when I just want to drink from a glass, and don't want to haul out my big ice bucket. I am convinced that YOU are the manufacturer to create the perfect mini-bucket for a chair-side refill. I would gladly be your first customer. Thanks! Read more
Good travel mug. Fits well in cup holders. Keeps drinks cold and holds ice for at least 24 hours. Read more
I bought this as a gift for my best friend because I loved mine so much and they are an avid coffee drinker like me. They were so excited when they opened it and saw it, it warmed my heart to know I chose well. I just love IronFlask! Works great for keeping drinks hot or cold all day long. Super easy to clean. Leak resistant if knocked over. Beautiful colors and texture, and affordable! Read more
