Thank you for viewing. I've made a compact rain cover that can be stored in a case for sudden rain. I made it to fit my viola case (Super Light) with a total length of 86cm, width of 30cm, and thickness of 14cm, but it can also be used for slightly smaller viola cases. Please refer to the images I've included, which show the cover fitted on my case, to get an idea of the size. Please note that it will be quite large for violin cases or rounded carbon viola cases without corners. There are stoppers at the top and bottom, and you can make fine adjustments with the buckles. It's made of thin, water-repellent nylon fabric that is wrinkle-resistant, lightweight, 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 things, so please ask if you have any questions. This is a one-of-a-kind item, so exchanges are not possible. Returns or exchanges due to customer reasons such as "the size didn't fit" or "the shoulder position didn't fit" are not accepted. Please check the size of your case carefully. * Although I make each item with care, it is a handmade product, so please refrain from purchasing if you are overly concerned about minor imperfections. Thank you for your understanding.
