We can cover all expenses on orders and replace the product with a new one or refund the money to the customer if our product is defective or damaged during delivery. All costs are covered by us. We can return money to the customer if they made a mistake when placing an order. However, the customer is responsible for the costs for delivery and returning the goods to us. The product returned must be undamaged and show no signs of active use. The product packaging must remain intact and undamaged. If the product has been used for a long time and has been damaged, we are unable to return the money to the customer, unless this product is defective and has deteriorated due to our fault. In any case, you can always reach out to us and we will study your specific case.
