Thomastik-Infeld VI01.12 Violin Strings - Premium Quality Strings for Professional Violinists | Perfect for Classical Performances & Practice Sessions

they play so smooth had cheaper ones they didn't do the job,i'm so pleased with these,order extras ,thats how much i love them too,give them a try worth the money use up to a year before changing thats a plus for me.練習用なので、安くて問題なし！安いものを探し見つけて購入。私としては十分使えますので問題ありません。
