RETURNS, EXCHANGES AND CLAIMS
Returns
We have a 14-day return policy, which means you have 14 days after you have received your item to request a return. To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. To start a return, you can contact us at info@sinecosine.nl. If your return is accepted, we’ll send you a return label and explain how to return your package. Items sent back to us without first requesting a return will not be accepted.

We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too. All discounted purchases are final and non-refundable.
