Due to popular demand, we have produced a 5-cartridge version. It has rubber supports, so you can store cartridges in any direction you like. I was looking for a cartridge keeper, but couldn't find the ideal type, so I made one myself. How about it for those who are looking for something similar? - Universal case, dark brown sheet, rubber supports. *Please understand that this is a handmade item before bidding. The wood grain pattern may vary as this is a sample product. Please refrain from bidding if you are looking for a perfect product. Shell/cartridges are not included. This is an auction for the case only.
