Can I cancel or modify my order?
Unfortunately, it is not possible to modify or cancel your order once it has been placed.
As soon as your order is completed, it is immediately processed in our warehouse to ensure the fastest possible shipping. This means we can no longer stop the cancellation.

If you do not wish to receive the order, you have two options:

• Refuse the package upon delivery – Inform our customer service that you are refusing the order to avoid any additional costs. FedEx / Royal Mail will then automatically return the package to us.

• Request a free return label – Once you have received the package, you can contact our customer service or create a ticket here to request a free return label in accordance with our return policy.
