New, unused double bass strings. Although there is no packaging, a shop clerk at a musical instrument store told me they were "Fortune" brand strings. I bought five sets in bulk, but I haven't used them all, so I've been storing them at home. They are made in China, but the quality seems to be good. I compared them to the Japanese-made "Cherry" strings, and I felt that these Fortune strings produced the original sound (a thick sound) of the double bass. I think they can be used not only for double bass but also for upright bass and silent bass. Shipping will be on days other than Tuesday and Thursday.
