Frequently asked Questions


The lids of our insulated bottles are evolving to adapt to new uses and to allow those who wish to easily equip themselves with an infuser. These new lids have been designed to screw on the infuser accessory directly and thus brew your tea, flavor or even purify your water. One cap rather than two: pre-equipping our insulated bottles with this cap also reduces our impact and avoids that you ends up with an accessory you do not need.

Started in 2022, this approach is progressive, some bottle models are likely not to offer this evolution yet.


Yes, you can put soft drinks in the Qwetch bottles.

Be careful when removing the lid, the pressure of the sparkling drinks could cause it to “pop”.

Also, we recommend that you clean the containers with hot soapy water after each use. For a thorough cleaning, you can use a bottle brush with warm water mixed with baking soda.

Sometimes some of our products are not customisable. But why? There are three possible scenarios:

  • Either it is a new product and it is currently being tested by our Alsatian engraver. If the test proves to be successful, it will soon be available for engraving;
  • Either the patterns of the design do not allow to clearly engrave the product;
  • Either the material of the product does not allow engraving (for example, our glass teapots are not customisable).

All year-round, we do our best to offer our Qwetch products at a fixed and fair price.

We have made the choice to offer our customers end of series on certain products that will not be renewed. Selection available on this link:

We are against unreasonable overconsumption and for sobriety. We encourage you to buy Qwetch articles or any other products, only if you really need them.

In a global context of rising raw material, transport and energy costs, our new 2023 tariff came into effect on February 1st. In order to make a success of the ecological transition we want to make, we wanted to limit the impact of cost increases on our consumer sales prices.

Thus, products dedicated to new uses, whose development will accelerate with the legislation, have seen their prices remain unchanged, particularly meal boxes and travel mugs. The price increases applied in February were limited to insulated bottles, whose retail price increased by an average of €1, with the exception of a few specific ranges for which a larger increase had to be applied to bring them in line with actual costs:
– The ROC range, with a particularly technical coating,
– The large formats, 1.5L and 2L, repositioned on a tariff more adapted to the reality of production costs,
– Products decorated in France.

Qwetch products are made by specialists, whose technics and raw materials guarantee a high level of temperature conservation, whether hot or cold. The vacuum insulated technology and the numerous quality controls, operated along the production lines, ensure these great performances, even on small volume capacities.
