Delivery Address

We can ship to most of the countries in the world. But PO boxes and military addresses (APO, FPO, DPO) can not be shipped to. Once your order has been prepared for shipment or has shipped, we are unable to change the shipping address. On the contrary, please contact us at within 24 hours of submission. If a package is returned to us due to an incorrect or incomplete address provided by you (the customer) or your agent, we will contact you immediately for a correction, and the package will be re-shipped at an additional shipping fee. And if any loss is caused by the wrong shipping address, it won’t be covered by the warranty policy. You must include a daytime telephone number for all orders. Occasionally packages are returned to Coolmetech as undeliverable. When the carrier returns an undeliverable package to Coolmetech, please contact Coolmetech to make arrangements for reshipment.

It takes longer than usual for delivery due to COVID-19, and the local post office may deliver your package to your door, your mailbox, or pick up points. Please keep an eye on the tracking information after your order is shipped out.
