The nation, product quantity, category, and color cannot be changed once an order has been placed. If you need to change these details, please cancel the order and purchase again. Due to different states and cities having different tax rates, we do not allow our customers to change the city, state, or ZIP code after the order has been placed when the order is paid for via credit card or bank transfer. If the order is paid for via Paypal or klarna, no changes can be made since the payment service provider verifies shipping address information before they approve payment.
