All hygienic products are provided and sealed with a hygiene seal. If this seal is damaged, the goods cannot be exchanged.
Hygiene has the highest priority for us, so we have to protect ourselves with this seal. This is necessary because we have neither the competence to trace a use, nor the possibility to clean the products according to our high hygiene standards.
We assume that it is also in your interest that you receive a product which is hygienically perfect.
