This is a 1/4 size fractional violin from ars music, which has a workshop in the Czech Republic. Purchased at a violin specialty store. I remember the purchase price was around 100,000 yen including the case. The violin case was purchased separately from Toyo Gakki. After sizing up, I loosened the strings and stored it at home. I believe it can be used if you have the strings replaced by a violin shop or a teacher. I will pack it as carefully as possible, but since I am an amateur, I appreciate your understanding.
