This is a Nahok oboe single case cover. It has a zippered pocket on the front. (Image 11) I don't remember when I bought it, but I acquired it a long time ago and have only used it a handful of times. The interior has some discoloration, likely due to age, but the exterior, including the corners, has no noticeable scratches or stains. However, upon close inspection, there is a black stain on the back. (Image 12) I don't think it's very noticeable, but please refrain from purchasing if you are concerned. External dimensions: Width: 36 cm Height: 21 cm Depth: 7 cm Please allow for some margin of error. I cannot answer questions such as "Which manufacturer's hard case will fit?" as I do not know the case sizes of all manufacturers. I believe that standard cases from Marigaux, Loree, Rigoutat, etc., will fit, but please judge for yourself based on the external dimensions. Please note that this item has been stored at home. I check for stains and other issues when listing the item, but I may overlook something. Please refrain from purchasing if you are sensitive to such issues. Recycled materials may be used for packaging. No claims, no returns. Please refrain from purchasing if you need the item urgently.
