Thank you for viewing. I made a compact rain cover that can be stored in a case in preparation for sudden rain. I made it to fit my viola case (Super Light) with a total length of 86cm, width 30cm, and thickness 14cm, but it can also be used for slightly smaller viola cases. Please refer to the images I took of it attached to my case for the size. Please note that it will be quite large for violin cases or round carbon viola cases without corners. There are stoppers at the top and bottom, and you can make fine adjustments with the buckles. It is made of thin, water-repellent nylon fabric, so it is light and durable. The storage pouch and decorative tape are made of slightly thicker floral nylon fabric. It folds up compactly and can be stored inside the case. I'm not very good at explaining, so please ask if you have any questions. This is a one-of-a-kind item, so exchanges are not possible. Returns and exchanges are not possible due to customer reasons such as "the size didn't fit" or "the shoulder position didn't fit." Please check the size of your case carefully. * Although I make each item with care, it is a handmade item, so please refrain from purchasing if you are sensitive to such things. Thank you very much.
