Thank you for viewing. I've made a compact rain cover that can be kept in a case in case of sudden rain. I also take made-to-order requests from stringed instrument workshops. This was made for a viola triangular case, approximately 86 x 30 x 14cm. It's for a SuperLight case, the older, thicker, and more robust type. It will likely be too loose for the thinner, smaller viola cases that are commonly sold now. Returns due to size differences are not accepted, so please be sure to check the size of your case. There are stoppers at the top and bottom, and the width can be finely adjusted with buckles. I used thin, lightweight, and durable plain black and a Nordic-style floral print fabric (both water-repellent nylon fabrics). 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" are not possible. Please check the size carefully. * Although I make each item with care, it is a handmade product, so please refrain from purchasing if you are concerned about minor imperfections. Thank you for your consideration.
