All hygiene products can only be returned unopened. If a product is opened, the goods are excluded from exchange.
Hygiene has the highest priority for us, so we have to protect ourselves with this strict handling. This is necessary because we have neither the competence to trace a usage nor the possibility to clean the products according to our high hygienic standards.
We assume that it is also in your sense that you receive a product that is hygienically flawless.
