Description The main problem with reusable straws is cleaning. They are difficult to clean without leaving residues and cannot be dried. This leads to the formation of germs and bacteria. Sliderstraw consists of two parts which, thanks to the patented construction, can be easily pushed in or out. After use, both parts can be put individually into the dishwasher and hygienically cleaned and dried – which is not possible with conventional disposable drinking straws due to their small diameter and closed shape.
