Calculation Result

While proxy bidding and purchasing services are convenient, overseas shopping carries certain risks. To reduce these risks, please read the following information carefully.
1. International Shipping
EMS: If the product status is not confirmed more than two days after arrival in Malaysia, a complaint case will be initiated and the issue cannot be reported to the seller.
2. After Receiving the Product

Please confirm and check the product as soon as possible, including specifications, quantity, accessories, and product description.

If you encounter any issues, please refer to the following examples:

Important Notes:
  • If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, any international shipping costs incurred for returns or exchanges must be borne by the member. Please refer to the postal service EMS e-Express fee inquiry. For alcoholic beverages or items affecting flight safety, postal service cannot be used and must be sent via DHL back to Japan.
  • During the complaint handling period, please keep the complete product outer packaging (including shipping label information), and do not repair or alter the original condition. Any changes will make the case unable to be processed.
3. After Checking the Product

After receiving and inspecting the product, if you have any questions, it is recommended to report to Letao within 2 hours. Here are the reminders:

  • Please do not open, use, or repair the received product by yourself, and be sure to keep the original outer packaging to facilitate subsequent processing and avoid situations where the seller is unwilling to handle due to product alterations.
  • You can call customer service, who will leave you a message and ask you to provide the following information:

    "Hello, Product ID: __________________ issue, we will first create a complaint case for you, but we need you to provide 2-3 clear photos of the product issue, including product issue photos, product packaging photos, shipping details slip, and outer box photos. Please send them to service@letao.my and inform us of your desired resolution method (failure to provide will prevent subsequent processing). After sending the email, please notify us in the customer service message, and we will confirm with the seller as soon as possible. After processing, if there are any related questions, we will contact you again. Thank you for your cooperation. Thank you."

    Please provide:
    1. "Product Number"
    2. "Packing Slip" photo (if any)
    3. Outer box photos (including inner and outer packaging)
    4. Product photos (since we are not professionals selling this product, please attach relevant explanations outside the image to help us confirm with the seller)
Important Notes:
  • The photo background must not contain Chinese characters or Chinese products.
  • Please keep the complete product outer packaging (including shipping label information), and do not repair or alter the original condition. Any changes will make the case unable to be processed.
  • Please provide the relevant information within 48 hours to avoid missing the golden time for reporting, which may result in inability to process.
  • Since 99% of Japanese sellers are unwilling to and unaware that products will be shipped overseas, if the seller is willing to handle the issue, the product must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will send the product back to Japan via EMS.
  • Since the product is purchased from overseas, when issues occur, it takes approximately one to two weeks to complete the relevant processing procedures. Please note that you can check the approximate cost at the post office's EMS service.
