The Distance Contracts Act stipulates that consumers have the right to withdraw their purchase without giving any special reason within 14 days from having received the goods. When you return a product to the seller you are liable to pay the postage. You cannot return personalized products, for example if a name is inscribed on the item. Download, fill in and print out the appropriate form from the Swedish Consumer Agency (Konsumentverket) web site.
You will find it here:
Items that are faulty or have been damaged in transit will be replaced.
If that is the case, e-mail email@example.com within 14 days of the receipt of the order.
