FREQUENTLY ASKED QUESTIONS ABOUT PRODUCT QUALITY

No. For the Turtleneck® Straw we only use food-safe, taste-neutral stainless steel of material quality DIN 1.4301 - the gold standard in the food industry, which can therefore be found in every kitchen. Cooking pots, drinking bottles and cutlery are also made of this stainless steel.

No. Our Turtleneck® Straw is made of stainless steel of material quality DIN 1.4301 - the gold standard in the food industry, which can therefore be found in every kitchen. The high proportion of chromium (18% - 20%) in combination with a high proportion of nickel (8% - 10.5%) ensure extreme corrosion resistance and dishwasher safety.

For the Turtleneck® Straw we only use stainless steel with the material quality seal 1.4301 - the gold standard in the food industry. It is a stainless steel that has a comparatively high proportion of chromium (18% - 20%) and nickel (8% - 10.5%). These two components make stainless steel an everyday material that can be found in every kitchen. Chromium ensures the corrosion resistance of stainless steel. In combination with nickel, the stainless steel becomes even more resistant.

Good to know: The nickel content is not a disadvantage! On the contrary: the higher the nickel content, the more dishwasher-safe and acid-resistant the stainless steel is.

To produce the Turtleneck® Straw, we only use food-safe stainless steel with the material quality seal DIN 1.4301. Unlike glass or cardboard, the corrugation makes it flexible and at the same time extremely stable and robust.

Definitely! Thanks to its maximum safety, its feel and the flexibility of the mouthpiece, the Turtleneck® Straw is also perfect for children, seniors and people with disabilities. Thanks to our high-quality, shatterproof stainless steel, it is free of toxic chemicals, pollutants, petroleum and BPA and will not shatter if you bite. That's why our Turtleneck® Straw has also been certified by Intertek® as mechanically safe and chemically safe.

Yes! Thanks to our high-quality stainless steel, our Turtleneck® Straw is free of toxic chemicals, pollutants, petroleum and BPA. The Tick Mark certification also confirms the quality. Independent third parties from Intertek® tested the product and ultimately demonstrated its ease of cleaning and mechanical and chemical safety. So you can be confident that you are receiving a safe product.

The Turtleneck® Straw can be used as a drinking straw forever even with normal use.

But of course nothing is indestructible – like everything in life. Even we cannot switch off physics. With a high bending frequency of hundreds of times per second, the resulting frictional heat can cause the material to become brittle.
