D'Addario Flat Mandolin Strings 3 Sets EJ74

This is a 3-set pack of D'Addario flatwound mandolin strings.
These are the standard Phosphor Bronze medium gauge strings for bluegrass, used by many professional musicians.
Purchased new from a music store and kept in storage at home. The packaging has surface tears from a price tag being removed, but the contents are unopened and new.
Although they have been in long-term storage, D'Addario strings come in sealed packaging, so I believe the contents have not deteriorated.
The price is 500 yen per set including shipping. As with instruments themselves, strings have been increasing in price more and more in recent years, so I believe this is a good deal.
No claims or returns, please.
