New Pirastro double bass strings, Original Flat Chromsteel 1 set (G, D, A, and E strings, one each). Chromsteel is said to have a powerful and strong tone, so I bought them to try, but I decided to use strings from another manufacturer, so I am selling these new. I bought them at a local musical instrument store for ¥96,360. They have been stored personally, so please check the condition of the outer bag in the photos. If you are concerned, please refrain from purchasing. There is a mark where the price tag was removed. Thank you.
