Dear Phunchita san,
Thank you for the shipping information.
Could you please amend the invoice as attached for import customs clearance.
We found that we can't pass the customs for duty free, because the return item is not put S/N and Made-in-Japan mark.
①SERIES WELD HEAD → SERIES WELD HEAD(UPPER PART)
②JPY240,000 → JPY120,000
If you have any questions, please let us know by return.
