3. Warehouse Locations
Our products are stored in both our U.S. and Global warehouses to provide more flexible logistics solutions. On each product's description page, we indicate the specific warehouse location.
3.1 U.S. Warehouse
For products stored here, we use USPS for shipping. Logistics within U.S. are very efficient, with an estimated delivery time of 3-7 business days.
