I Bought for 14 keys, lower end of range, got offers of black/white bills. Maximum was an earbud if I added 14 keys=26-14=12 keys (link1). Eventually sold at 13 keys in trade server. Link 2: Max was black bills + kringle = 12 key. Link 3: highest is ts bills + 4 keys = 13 keys. Link 4: offers of 10 keys and highest was black bills kringle = 12 keys. Link 5: Black Bills + Kringle is his only offer = 12 keys.
