As a dedicated B2B trading vendor, we provide formal commercial invoices, detailed packing lists, and official proforma invoices (PI) for all bulk wholesale transactions. These transaction documents will be generated by our finance department and sent directly to your registered business email or via WhatsApp once payment terms are verified.

Because we deal with bulk B2B commercial shipments, we do not support unconditional consumer returns. However, we offer a comprehensive 12-month quality warranty on our smartwatches, audio devices, and power banks. If any functional manufacturing defects are found in your batch, we provide direct replacements or credits in your subsequent wholesale order.
