Thank you for viewing. This is a full set of strings for a Helicore medium scale (380-405mm). They have been used for about a year, so some discoloration can be seen. They were on a sub-instrument and used until recently, so they are still usable, but since a year has passed, they are recommended for those who want to try Helicore strings. Please check the condition in the images. There is no outer bag. They will be packaged with bubble wrap or OPP and shipped via Yu-Packet Post Mini.
