Shipping Notice for Orders to the United States

Shipping Notice for Orders to the United States

Thank you very much for shopping with us.

Please kindly note that orders placed on or after December 17 will be shipped after January 6, 2026.

Recently, many shipments to the United States have been held at customs, and there is a risk that parcels may be returned to us during the year-end and New Year holidays when our office is closed and unable to respond to customs inquiries.

To avoid this issue, we will temporarily pause all shipments to the U.S. from December 17 to January 5.

Orders can still be placed during this period, but shipments will resume on January 6.

We sincerely appreciate your understanding and cooperation.
If you have any questions, please do not hesitate to contact us.
