If, for example, the Browband is within 30 days of purchase and has NOT been damaged due to wear or other external causes, then you can go to the SHIPPING AND REFUNDS section and return it for free. If, on the other hand, the product is damaged due to wear, then contact us via whatsapp and we will agree if it is possible to repair it. The cost of the repair (12 euros) plus shipping (12 euros) will be paid by the sender.
