This is a set of 4 Pirastro Original Flexocor strings. The price of strings has been increasing year by year due to rising costs. ・Condition of each string G string...Some roughness D string...Slightly stiff A string...Soft E string...Soft Slight deterioration on the peg side (see photo) The G and D strings are slightly deteriorated, so they are listed as having some scratches and dirt. I no longer plan to use them, so I can sell them at a low price. Please feel free to negotiate the price. Recommended for those who want to keep them as spare strings or try them out. I will clean them before shipping.
