PIRASTRO FLEXOCOR Contrabass String Set of 4 - Brand: PIRASTRO - Model: FLEXOCOR - Type: Contrabass Strings - Quantity: Set of 4 Thank you for viewing. I am selling a set of "Flexocor" contrabass strings, orchestra tuning, that I used for just under a year. There is some slight twisting, but the sound quality is still fine and they should still be usable. One of the most popular steel strings for orchestras. Known for its warm and soft tone. The short reverberation and quick attack make it particularly suitable for arco playing (from the Mac Corporation website). I will ship the strings in their original bags, then placed in a brown envelope. However, the string bags are dirty and torn. I would appreciate it if those who understand that these are used items would consider purchasing them. New, regular price: ¥69,520 (refer to Kurosawa Strings)
