About Flask
If Flask has anything to say about it, disposable packaging will be a thing of the past as soon as possible. The future is reusable! At Flask, you have come to the right place for reusable bottles, cups and mugs in all shapes and sizes. Developing and discovering innovative reusable products is what drives Flask. They are constantly searching for new materials that are as environmentally friendly as possible and, above all, are durable.
In addition, Flask supports various foundations in their fight to preserve the planet. As an ambassador of Made Blue, Flask donates 1,000 times the content of the bottles sold per order of at least 250 units. So let’s do the math: with an order of 250 bottles of 500ml, Flash donates 125,000 litres to Made Blue’s projects.
“
“We were looking for a charity that helps developing countries combat the use of disposable water bottles in a sustainable and transparent way. We decided to support Made Blue because it is very clear what happens with your donation. We can now show our customers exactly how many litres of water has been donated and how much waste has been saved.”

Personalise sustainably
Flask offers the option to have products personalized as desired. By using inkless techniques or reusing ink, the printing process at Flask is as sustainable as possible. That is why a reusable Flask product is a great promotional gift that radiates social involvement.

One litre for one litre
In our program One litre for one litre you can convert the water saving or water consumption of your product, service or organization into an equal amount of litres of clean drinking water in developing countries. Choosing a selection of customers or donating more litres is also an option. Transparency is paramount and we are happy to help you communicate about it!
