Thank you for viewing. For organizing violin accessories: ● Violin Bowing Guide Corrector 4/4 - 1/2 HorACE Bow Guide Purchased in 2015, ¥2,570 I bought this when I started learning, but I think I only used it once. It didn't suit me, so I kept it stored away. I would like to give it to someone who can use it. Please refrain from purchasing if you are overly sensitive or concerned about minor details.
