I know it's boring as hell, but all I want for my 120ii is a black, smooth leather case like I had for my AK100. I remember I had to order that from a Korean seller on eBay, and it wasn't cheap.
Yup, I've just got an AK120 II, and the case is functional, but I very much prefer the stock case shipped with the AK100 II (the smooth, clear leather case).
