B&H would not support 3850. they must be 3880 or 3800.
If non-OEM inks is one of your options, I would suggest you take a look at InkRepublic's 38XX i-Refill inks and kit. 3850 is not US model, so I assume you are in oversea, perhaps Japan or Asia area? They do ship to oversea without extra charge and very likely they do support 3850 model as well. (Perhaps the only company supports 3850 system). Their latest IRK4 inks are wonderful, no clogs, and ABW-mode is perfect! Photo BlacK is superb in blackness too!
they do ship to other countries, so I believe they can support you 3850.
