Can I return my Onatural Pump if I change my mind?

Onatural Pump is an intimate product. For hygiene and safety reasons, it can only be used by one person. 

This means that once the tamper seal is broken, you will not be able to return it to us or to a retailer unless it is faulty. Please refer to our Terms of Sale for full details about your rights. 

For your peace of mind, the Hub (pump mechanism) has a one year warranty and the washable components have a 90 day warranty.

We also have a Customer Care Team who are ready and waiting to help you through your pumping journey.
