YAC KEN様
Good morning.
I’m terribly sorry for the confusion.
This is our YTK’s manufacturer’s number.
We want to write this number so that we can identify this shipping is what.
Next time, we’d like to write YTK’s number with bracket( ). How do you think?
ex.Customer’s PO number( YTK’s number )
Thank you,
Chihiro kobayashi
