IRON °FLASK Classic Tumbler - 710 ml, Vacuum Insulated Stainless Steel, Hot Cold, Double Walled, Thermo Travel Mug, Water Metal Canteen (Black Marquina)

Love this flask used on holiday for 2 weeks to keep drinks cold - it literally keeps them cold so long - ice cubes still left the next morning! Such a pretty pattern too. Not leak proof as such as the lid has the hole for the straw. Easy to clean and great that it comes with the straw cleaners too. Only downside I’ve noticed is what looks like rust forming around the outside down by the bottom ring which doesn’t impact anything inside so wouldn’t contaminate drinks but just doesn’t look as good as when I bought it and only 2 weeks old.

I've been trying to get myself to drink more water and this has been a great help. Will keep a drink cold wonderfully, maintaining a low temperature even hours after filling. I really like the sleek black and brushed metal look which has a subtle texture to it which means it won't slip out of your hand either. Only thing I can really complain about (Of which it is a very minor one) is that I think the advertised capacity is without the non-spill lid on. I have the 24oz (Approx 700ml) but with the lid in place it will only hold around 650ml. Would still highly recommend, super easy to clean with the included brush for the straws and does a great job at keeping drinks cold. I feel like I drink out of this and nothing else now

Nice tumbler, well made, comes with spare straws and cleaner. Easy to get lid on and off (push seal not screw) keeps drinks cool for a while.

In need of a tumbler as the one I had was plastic with paper on the inside. The paper was molding and the lid was chip so wanted something more durable. This is worth every penny. My drink is cold for most of the day. It won't keep it cold the full 24 hours like the water bottles as there's a hole at the top for the straws but it's definitely long enough to finish your drink. And I love the colors. Very high quality flask, comes with 2 metal straws, 2 plastic black straws and straw cleaners. Highly recommend if you drink water constantly like I do.

It's a great cup holds hot drinks cold drinks lid keeps it hot for ages

Love this cup especially now it’s warmer at night. Take iced cold water to bed every night and still nice and cold in the morning. The size is perfect and definitely value for money.

I purchased the 32oz tumbler in winter White as it was on deal, and needed a new one as my old one had begun leaking. Now this is a tumbler and does not have a lid that is leak proof as it has a sipping / straw hole and a small air escape hole for when you drink. I knew this prior, but wanted for my car (VW Golf) - this fits in the cup holders in the centre console perfectly, no wobbling or tipping. Easy to clean. Not used the plastic or stainless steel straws yet, but they come with mini cleaning brushes so should last a lifetime. Definitely recommend if you're able to keep it upright e.g. at a desk, in your car (check it fits with measurements) etc.

Absolutely loved this on holiday, went to the Caribbean and it kept the drinks cold all day. Still ice in there the next morning when I woke up. Amazing! This is a fab bit of kit to take away on a trip! Will definitely 💯 reccomend. Quick delivery great, vibrant colours, metal and plastic straws included. Love love love

I basically drink iced tea all day long. Until I bought the Iron Flask, I'd been using a Teva double-walled plastic tumbler, same size as the new Iron Flask, 24oz. It was physically bigger, tended to tip over, and didn't especially keep my tea cold for long. Plus it was awkward to hold for someone with small hands like mine. The Iron Flask holds the same amount of liquid, but I can go hours without the ice melting. In fact, I've had to adjust how I serve up my tea because I no longer need 1/3 a glass of ice to keep my iced tea cold. Also, upon occasion I still have part of a glass of tea when I'm ready to go to bed, so I'll put it in the refrigerator overnight. Only with the Iron Flask, there's nearly always still lots of ice in there the following day (unlike the Teva where it would always be entirely melted by then). I haven't been using the included lid or straws yet, but I guess I might at some point. They do all look pretty nice, especially the steel straws. The lid doesn't screw on, but has a rubber gasket to keep it in place; I actually prefer this over the usual mugs which often have raised threads for screwing on the lid. Looks nicer this way, in my opinion. The reviewing thing here wanted me to rate whether it was "leak proof"—and the answer there would have to be no, because the lid has a hole for drinking or for inserting a straw, and another smaller hole for ventilation while drinking. So, if you tip it over, yes, liquid will glug right out. (On the other hand, 'tipping over' seems to be less likely with this tumbler than with my old Teva. Perhaps because with the Iron Flask, it's still pretty weighty even when empty.) Anyway, I'm very happy with the Iron Flask 24oz tumbler. It's a great value for the price, attractive, holds plenty of liquid, and does a great job keeping cold drinks cold. (I can't speak to hot drinks because I haven't used it for that.) I'd definitely buy it again.

Ottimo prodotto, peccato che manchi un tappino per chiudere la bibita quando non si beve

Love the design, capacity and differently angled stainless steel straw options!

Excellent quality

I loved this tumbler at the beginning. Sturdy, kept things coldish and I loved the different straws and cleaning tools but... after about 2 months I noticed that a seam in the rubber seal had torn. This causes the seal to flip about everytime I refill the tumbler and I have to manually adjust it (everytime). I would have loved if it also included extra seals!!! Are the seals replaceable?
