**Note
- The system will send the first email to apply the electronic seal. You can use the certified tax invoice with the time stamp in the subsequent email.
- The document cannot be changed or edited. Please check that the full name and ID number (as requested) are correct and complete.
- We reserve the right to refuse returns/exchanges. (If you are unsure about the size or product, please request the e-tax invoice only after receiving and trying on the item to ensure it fits.)
- For E-Tax invoices from Marketplace channels, the amount on the tax invoice will not match the actual amount you paid, as the price received by the store does not include discounts provided by the platform.
