Company Reviews

Happy to see that our employees don't use plastic waste bottles anymore and they are super proud to walk with this sustainable bottle with sportlid. The bottles are from high quality and look amazing. Thereby, the motivation to drink more tap water gets easier.


We started with a personalized Dopper, but soon discovered that it was leaking and started to mold. Then we switched to FLASKE and this bottle is so much better. We get a lot of compliments about it. Our employees use it all day, which is good for our brand awareness. This way they all see that we contribute to clean nature and opt for sustainable.


We decided to treat all our employees to a branded and personalized water bottle for a Christmas gift. The engraved logo and names look perfect and the water bottles are very high quality. The ordering process was very smooth and Ruben from FLASKE made sure that everything worked out well and in time for our Christmas party. I can highly recommend and would order again.
The whole team loves the present, since everyone can use a cool a water bottle and I love seeing the bottles dotted around the office!

There are many aspects to our future like a healthy planet. In line with this thought and this year’s MVO initiatives within Cardano we wanted to give our colleagues a special Christmas present. With this in mind we found FLASKE. No more plastic bottles/containers. We have made our office more sustainable with the bottles and the foodpots of FLASKE. Beautiful designed and personalized with name and logo. Thank you FLASKE for the great service and communication.


FLASKE has created a great Christmas - New Year gift for all our employees! Thank you!


We are very happy that we have chosen for FLASKE this year. All employees were surprised and they use their bottle every day. No more plastic bottles on our desks but a good looking reusable FLASKE. Good quality bottle with a presentation: the black bag and the roundbox are super nice. We would highly recommend FLASKE!

We are very happy with FLASKE in Pharmacies Amsterdam Center. Previously, many plastic bottles were used. The colorful bottles are also very useful for tea or cold drinks! Tip: engraving the names was extra fun for the employees.

For our medical consulting firm we have, for customers, ordered personalized FLASKE bottles with engraved company logos. The reactions where amazing and the message to society, to which a contribution is made to combat plastic waste, was greatly appreciated! We have also ordered bottles for our family.

Employees of Intervest Offices & Warehouses are often on the road. Every time they open their FLASKE instead of a plastic bottle, they contribute to the reduction of plastic. But why exactly a FLASKE bottle? Well, FLASKE is frontrunner in sustainability with many possibilities to customize products and they provide excellent service. FLASKE's sustainable mission was really the deciding factor. A better world starts with ourselves, doesn't it?


I was looking for something better to offer my clients, something permanent and with a charity that I believe in and make a difference! I found FLASKE, in addition to being a stylish, beautiful bottle, they are supporting a charity. Good customer service and high quality products!


This we took the step to become more sustainable. Everyone is drinking a lot of water at our office and what is better than a good looking FLASKE with all the nice features. The support of FLASKE and the quality are beyond imagination. Everyone is using the FLASKE every single day!



The white bottle including the special lid is something to be proud of. Everyone is drinking more tapwater than ever!


From now on we are only using the FLASKE products for our giveaways for the employees, relations and event. Everyone loves the FLASKE and it is also very good for our visibility while everyone is using the products daily and everywhere.


We surprised our employees this year with a branded FLASKE. The communication was clear and the bottles came earlier than expected.


Very happy with the quality and good service. Would highly recommend this brand.

Drinking water from a plastic bottle is not from this time anymore. That is why our employees have this branded bottle. This looks much better on our desks than a plastic bottle and it is a eye catcher when we visit our clients.


We love the color and the presentation! The luxury packaging was a surprise for all our employees. 10/10!
