Set of 4 double bass strings: Spirocore Light E, A, D, G. Used for about 6-7 months. Non-smoking environment, no pets. The felt at both ends is frayed, but there are no bends at the contact points with the bridge. I think they can still be used. Cleaned and disinfected with alcohol. These are standard Jazz strings, but I think they can also be used for classical music and other genres. I have discarded the original bag, so I will ship them in a different bag. Also selling on other apps. Please note that they may sell out depending on the timing. Double bass Wood bass Double bass strings
