How does a flask work?

Flasks work by not allowing heat to transfer. The coating on the inside of the bottle stops heat transferring through radiation, and the vacuum seal prevents heat escaping by convection. This means your hot drink stays hot!

How do I clean a flask?

Cleaning your flask isn't actually as hard as it looks, but if you're not sure, then let us talk you through it! Make sure the flask is empty first and then put some baking powder into the flask, and pour water from a recently boiled kettle over it. Once the foam has settled, cover it over and leave it for about half an hour. If required you can repeat this, but this should remove difficult to reach tea and coffee stains!

Hip Flask

Hip flasks are normally much thinner than other flasks and are used to bring your favourite alcoholic beverage with you. The standard choices include port, whisky, gin and brandy. Whatever you're looking to put in your flask, we've got great deals for you here at Wowcher! You can get yourself a personalised hip flask or treat a loved one to a nice gift with their name on!

Sustainable Flasks

If you're looking for ways to help the environment, you've come to the right place. We have some amazing deals on flasks and mugs made from bamboo. The products are created from sustainably sourced organic bamboo, which is much kinder to the planet and lasts longer! As they are double walled, they will keep hot drinks hot for 10 hours and cold drinks cold for 24 hours! You can even get these personalised with your own name or a loved one's name if buying as a gift!

Stainless Steel Flasks

This is similar to the hip flask, but alcohol isn't really used in these flasks. We have great deals on these including our 150ml stainless steel flask, which is suitable for hot and cold drinks due to the vacuum seal. As it's a small capacity, it's great for shorter journeys to keep you going. You can choose from five colours including black, red or blue. This would make a great gift for a loved one or a little something to make your journeys a bit easier.

Thermos Flask

Thermos flasks keep your hot drinks hot for longer! With our thermos flask, your hot drink will still be hot six hours later! You can easily chuck this in your bag or your car and we can guarantee that there will be no leaks or spills! You can also keep your water cold in this flask! Shop our thermos flask deals, and choose the colour that suits you best. Then you can sit back on your journey or in the office and relax with a hot drink!
