Flow Jewelry Studio ships on the account of its clients. Authorization letter is requested for our files and we ship based on clients preference. Please note through experience the preference of Flow Jewelry Studios is to ship with UPS. We also ship registered mail which can be tracked and is more affordable but it must be noted that Flow Jewelry Studios ships on behalf of the client based on the clients request and can not be liable for lost or damaged shipments. As a note we have had the utmost success with out issue using UPS. Using both UPS and Priority Post / EMS where both are trackable and no lost or misplaced shipments in our history of shipping Jewelry globally.
