A set of Thomastik Spirocore light tension orchestra tuning (GDAE) 4-string double bass strings. I purchased these as spares and have kept them in storage. They are new and unopened. I am selling them because I want to try other strings. Immediate purchase is OK. They will be shipped in a Nekoposu (Japan Post) dedicated box. Returns are not accepted. From February 1st next month, there will be a price revision for THOMASTIK strings, and prices are expected to increase, so please consider purchasing soon. #DoubleBass #DoubleBassStrings #WoodBass #WoodBassStrings #Spirocore #LightTension #JazzBass #LightGauge #SPIROCORE
