Pirastro Original Flat Chromesteel strings for orchestra tuning (GDAE) set of 4. I purchased these new and used them for about 2 years. I think they are still usable, so I recommend them to those who want to try them out. I will pack them in a plastic bag and wrap them with cushioning material. I have attached and detached them several times, so the E string has some fraying of the steel winding and the felt winding part (photos 6 and 7). Retail price: Approximately 85,000 yen Features: Heavy sound, produces a large volume. Contrabass, Original Flat Chromesteel, strings, wood bass, double bass, stringed instrument, Pirastro
