Large mug and soft base pad, make it a practical and attractive choice

This flask is no doubt a stylish and eco-friendly solution for keeping your beverages at the perfect temperature. Its innovative double wall thermal insulation ensures drinks stay hot or cold for over 12 hours. This impressive performance applies to both the 700ml flask and the attached cup, making it ideal for long trips, office hours, or any activity requiring temperature control. One of the standout features is the large, satisfying 300ml mug included with the flask. With a capacity to fill over two full cups, it's perfect for sharing your favorite drink with a friend. The convenience of having such a spacious cup attached is unbeatable, especially for those who enjoy larger portions or need to serve multiple people. The soft pad on the base of the flask is a thoughtful addition, ensuring safe and silent placement on any surface. This makes it a great companion for home, office, or on-the-go use, as it minimizes the risk of scratches or noise when placing the flask down. The attention to detail in design truly shines through here.
Although this flask isn't without its flaws. The shaped and machined lid, while providing a secure grip for a leakproof seal, can be somewhat difficult to open, especially for those with weaker hands or in cold conditions. Additionally, the hidden magnets that attach the cap to the flask may lose their strength over time, potentially leading to a less secure fit.
Despite these minor drawbacks, the overall quality and functionality of the Flask make it a worthy investment for anyone in need of a reliable and stylish beverage container. Its ability to maintain temperature, combined with the large mug and soft base pad, make it a practical and attractive choice. Whether you're at home, in the office, or on the go, this flask is designed to meet your needs with a touch of elegance.

Tea with no sugar please !

🔹INTRO & DESCRIPTION🔹The ION8 Vacuum flask is available in various colours. I was torn between the green (my favourite colour), and the navy blue (more neutral). In the end I actually went for the deep teal shade, which is the best of both worlds.The flask has a large capacity 300 ml cup, and the container itself holds 700 mls meaning two people can have a brew each. It has a textured surface making it easy to grip. The cup attaches magnetically to the flask, and the liquid is secured in the flask with a **** top.🔹OPINION🔹&🔹CONCLUSION🔹Firstly, after my dilemma over the colour, when the flask arrived I was delighted with my choice. The teal is lovely, and the silver band really sets it off.The textured surface is a great idea, and makes it easy to grip if your hands are cold/wet or if you are wearing gloves. There is a rubber pad on the base which ensures it doesn’t bang when you put it down.The cup is much larger then the one on my previous flask, which is perfect as I do love a good decent sized cuppa !I mainly chose this flask as I have recently taken on an allotment, so it’s great to look forward to a nice hot brew after toiling away in the cold. I can either go on my own and enjoy two brews, or if my partner comes along he can have a brew with me. As well as tea, it will also hold coffee or even soup (though I have not yet tried it with soup). Being made from stainless steel it’s also durable. Just make sure you don’t pick it up with the cup – it is magnetic and holds secure, but not secure enough to pick the flask up when full.I can think of many opportunities for using this flask, not just on my allotment, but also on trips out. I just need to make sure "him indoors" doesn’t take a liking to it when he resumes his fishing – he'll have to buy his own !

Awesome flask, keep stuff hot and feels well made.

I have heard good things about ION8 before and this pretty much echo's that. The flask feels really sturdy, the cup is held on I think magnetically, and unlike many is actually really nice to drink from. The flask itself keeps the contents hot for ages. This seems like one of those flasks that you hold onto for ages no matter how battered and dented it becomes.
