Customized products, such as those with a customized variation or personalization, are not eligible for return or exchange. This is because they are produced specifically to meet the individual customer's specific requests and preferences. When an order is placed for a customized product, the customer is agreeing to the terms of the purchase, including the fact that the product cannot be returned or exchanged. It is important to carefully consider all aspects of a customized product before placing an order, as the right of return or exchange does not apply in this case. It is the responsibility of the customer to ensure that they are satisfied with their order before it is finalized and produced.
