How do I return an item via the right of withdrawal?

If the right of withdrawal applies, the Buyer is entitled to a withdrawal period of 14 days to cancel the sale, without stating reasons. This withdrawal period starts on the day on which the Buyer or a third party designated by the Buyer takes physical possession of the product. The Buyer must unambiguously notify the Seller of its wish to withdraw from the purchase within this 14-day period, in accordance with the withdrawal form.
