    Expectional service, transparent approach and great prices

    Last month, I ordered from HelloPrint for the first time (it was recommended by our event organizer/partner), and I was very impressed with how smooth the process was. I always get anxious when dealing with printing vendors—worrying about whether the leaflets will arrive on time, in good condition, etc. I spoke with Michael from their team because I was placing an order from Slovakia that needed to be delivered to Spain (and therefore via their Spanish website and I don´t speak Spanish). At first, I felt a bit lost, but Michael made everything effortless, and I knew my order was in good hands. I also have to highlight HelloPrint’s transparent approach to timelines—clearly outlining when to submit visuals, when to review and approve them, and how each step affects the delivery date. To sum it up, I will definitely be ordering from them again. Plus, their prices are unbeatable, which makes it even better for me! :) Thank you, HelloPrint and Michael!

Frequently Asked Questions about our Thermos Flasks

What is a thermos flask and how does it work?

A thermos flask is an insulated container that keeps liquids hot or cold for extended periods. It works by using a double-wall vacuum insulation that minimises heat transfer, ensuring your drink remains at the desired temperature.

How do I clean my thermos?

To clean your thermos, fill it with warm soapy water, secure the lid, and shake it thoroughly. Use a bottle brush to scrub the interior, rinse well, and let it air dry. Avoid using bleach or abrasive cleaners to maintain the flask's quality.

Are stainless steel flasks safe for drinking?

Yes, stainless steel flasks are safe for drinking. They are made from food-grade materials, resistant to rust and corrosion, and do not retain flavours or odours. Ensure your flask is BPA-free for added safety.

What are the benefits of using a thermos water bottle?

Using a thermos water bottle helps keep your beverages at the desired temperature for hours. It's eco-friendly, reduces plastic waste, and is convenient for outdoor activities, travel, or everyday use.

Can thermos flasks keep drinks cold as well as hot?

Yes, thermos flasks are designed to keep drinks both hot and cold. The vacuum insulation technology maintains the temperature of your beverages, keeping them hot for up to 12 hours and cold for up to 24 hours.

How do I choose the right size thermos bottle?

To choose the right size thermos bottle, consider your daily hydration needs and usage. For daily use, a 500ml bottle is sufficient. For longer trips, consider a 1-liter bottle. Ensure it fits in your bag or cup holder.

How long can a large thermos flask keep beverages hot or cold?

A large thermos flask can keep beverages hot for up to 24 hours and cold for up to 24 hours, depending on the brand and insulation quality. Always check the product specifications for precise details.

Are water flask bottles good for hot drinks?

Yes, water flask bottles are good for hot drinks. They are made with double-wall vacuum insulation that maintains the temperature of hot beverages, ensuring they stay warm for hours without burning your hands.

What is the difference between a thermal bottle and a regular water bottle?

A thermal bottle is insulated to maintain the temperature of your drinks, keeping them hot or cold for longer periods. In contrast, a regular water bottle lacks insulation and does not maintain drink temperatures effectively.

How do I prevent my thermo bottle from smelling?

To prevent your thermo bottle from smelling, clean it regularly with warm soapy water. Rinse it thoroughly and let it air dry with the lid off. For stubborn odours, use a mixture of baking soda and water to scrub the interior.
