Purchased from Erhu Hime. Price: 2640 yen (tax included) The lining has a non-slip material, which can be used to prevent slipping while playing. This cover was a limited summer color. The white fabric with blue embroidery is beautiful. It's a glossy fabric. I used it for a while, but I switched to another one, so I've been storing it at home. There are no noticeable stains or damage, but the corners of the folds are slightly darkened as shown in the last photo, but it's not very noticeable. There is some wear and tear. Also, I have a cat at home. Please refrain from purchasing if you are sensitive to this. I will fold it for packaging, so there may be some creases. Used as a cover when storing the erhu. ⇒ Prevents rosin from the bow hair from sticking to the strings during storage, reducing stickiness and protecting the strings. Used as a non-slip material. ⇒ One side is made of non-slip fabric, so it can be placed under the erhu during practice to prevent slipping. As a result, the erhu will not move, allowing you to maintain the correct playing posture and making it easier to play.
